A loot close a packet owed was made at the frame's end (`drain_loot`), so a listener between two packets saw the window open, and the release went out late. 1.12.1 closes it inside the packet, at `EndLootWindow` (`0x48f200`).
**Changed**
- A precast end, a GO, a cast result, a move start and the server's stand state each close the window inside their packet. Each release goes ahead of the handler's later sends.
- Every close cancels the rows' pending record fetches (`0x4c1cb0`). A move or a sit closes only while a loot target is latched (`0x6126b0`).
- A chest's GO arms its loot target after the close (`0x6e831b`).
- `drain_loot` is gone. With it, the last frame-end write a listener could read is placed.
**Tests:** each close inside its packet, the release order, the latch gate, the fetch cancel. Each fails on main.

A remote unit's move was seated by the frame's movement pass, so a listener between two packets read where the unit stood before. 1.12.1 seats a move inside its packet when the movement clock has it due (`0x618dd2`), and holds it for the tick when not.
**Changed**
- A due move seats in its handler, stepped on by its lateness (`0x618bb0`). A rider seats on any game object flagged as a transport (`0x630a80`).

A follow ended at frame time, in `steer_follow`, and AUTOFOLLOW_END fired there, out of order with the packets that ended it.
**Reference:** `StopAutoMove` (`0x60fb60`) ends a follow inside the packet that ends it: our death, the attack-state swing, the taxi flag, a mover switch or release, a near teleport, a knockback, feign death, a stun, a monster move on us and far sight. It signals AUTOFOLLOW_END (`0x60fb84`), then releases forward and autorun. A near teleport and a knockback also close the loot window (`0x60e990`).
**Changed**
- One stop runs at each of those handlers, with END on the notice lane and the autorun clear behind its listeners.
- The loot window closes on a near teleport and a knockback.
- Each unit holds its client-controlled bit (`0x5fa636`).
- `feed_follow` is gone.
**Tests:** each end fires END between its neighbouring packets' events, and death's END comes before PLAYER_DEAD.

The bar's usable pairs were stored by a per-frame diff, and EditMacro's and a bag update's refresh fired at frame end, so ACTIONBAR_UPDATE_USABLE and a slot's IsUsableAction lagged their cause.
**Reference**
- Each slot write stores its pair (`0x4e58e0`, `0x4e590a`).
- The refresh `0x4e5c00` runs at world entry, inside EditMacro (`0x4f132e`) and in the item watcher's run before BAG_UPDATE (`0x4f9374`).
- Game entry zeroes the cache (`0x4e4f50`).

The Craft window answered from a copy a feed refreshed once a frame, and rebuilt and signalled there.
**Reference**
- The build (`0x4f60c0`) zeroes its counts and, with no craft type open or no player, leaves before CRAFT_UPDATE (`0x4f661a`). The open, SMSG_PET_SPELLS, the record callback, learn and unlearn, and the item watchers rebuild it.
- The getters read at the call (`0x4f6c3b`, `0x4f6d52`, `0x4f6fe6`, `0x4f76b2`, `0x4f7a3c`).
- GetCraftDescription falls back to the taught spell's text (effect 36 or 57), with the pet flag (`0x4f7b53`).
**Changed**

With the targeting cursor up, a unit a packet selected was parked and bound to the cursor a frame later. A spell's deferred swing at its go also skipped the attack validator.
**Reference**
- `SelectTarget` with the cursor up binds at once (`0x4935d5` → `0x6e5b40`) and selects nothing. The loot response, the two acquires and the go each reach it at their packet.
- The go's swing runs the validator `0x612df0` (`0x6131aa`): the actor checks, the select, then the reload from the selection (`0x6130c1`), with ERR_NO_ATTACK_TARGET or ERR_INVALID_ATTACK_TARGET.
**Changed**
- Each handler binds in place.
- The melee probe and the pet bind inside their press.
- The go runs the Attack action's validator and swings at the selection as reloaded.
**Tests:** the loot response binds between its neighbours, a stunned caster's go sends no swing, and with a cursor up the go binds one unit and swings at the selection.

The movement verbs and DropItemOnUnit queued their work for frame time, so a cast a movement press should cancel was still running on the script's next line.
**Reference**
- Every movement verb goes through `SetCommands` (`0x515090`). It sets the bit, and a new press in mask 0x10f0, or the press completing both mouse bits, cancels the cast inside the call (`0x51512a` → `0x6e4940`), then the channel, then runs the tick.
- ToggleAutoRun reads the bit at the call (`0x513de7`).

The action bar's state getters and cooldown queries answered from a copy the feed refreshed once a frame, so a call made between feeds read the last frame's state.
Reference: each getter reads its slot at the call. A cooldown query that misses the item cache registers a callback on the record (`0x6e2f70`) and answers when the record arrives. A pet spell list derives its macros where it loads (`0x4bdae0` → `0x4f0ce0`). The go handler sweeps both cooldown lists every 120 s (`0x6e1910`); the insert sweeps nothing.
Changed: the bar getters (IsUsableAction, GetActionCooldown and the rest) resolve and read live. The cooldown query uses the record's callback list. The pet list derives its macros in its place. The sweep moves to the go.

Several verbs did their work in a later drain: try-ons, the chat input's /target, /assist and /follow, RestartGx, and the engine CVar verbs (SetGamma, the video pairs, SetMultisampleFormat, the minimap zoom, the glue writes). A script's next line read the old state. LoadBindings also switched the current set, so a Character Specific tick then Cancel left the character set live.
Reference: a try-on reads the cache and lands or refuses in its call (`0x504540`, `0x504b2d`). RestartGx runs gxRestart synchronously (`0x48dab0` → `0x63ce00`), and SetMultisampleFormat restarts in its call (`0x48c79b`). LoadBindings never writes the current set (`0x4b8249`-`0x4b8252`).
Changed: those verbs apply in the call, and the slash commands call the stock verbs. The drains left at the frame each name why; SaveBindings only marks its set until shutdown (`0x4b6310`, `0x4b65e0`).

- the vendor and trainer lists (`0x4fad32`, `0x4d74ae`);

A profession's book opened from a frame feed, after the cast verb had returned, and its "Create All" repeat recast from a drain. A listener read the book shut inside the call that opened it, and a repeat on a recipe with a cooldown refused its own recast.
Reference: `TryCastSpell` opens the book inside the call (`0x6e4bce` → `ToggleTradeSkill` `0x4fc910` / `ToggleCraftWindow` `0x4f6000`). `HandleSpellGo` runs the repeat hook (`0x6e81e7`) before its cooldown inserts (`0x6e8425`). The repeat disarms only at a failure report, a failed cancel, or the close (`0x4fd790`'s four callers).

Reference: the unlearn handler clears the spell's slots after the book removal (`0x4e5e20` at `0x5ea253`). The supersede's `0x4e5e60` clears then sets each slot, with a send and an ACTIONBAR_SLOT_CHANGED for each (`0x4e58e0`). The learn and unlearn set the latches (`0x4b262c`, `0x4b2c83`).

An item record's answer ran its callbacks from hand-placed hooks. The equip replays ran in the drain, the quest log's refire at the frame's end, and the tooltip rebuilds at the tick, so a replay's send followed later packets' sends. A refused record also replayed every frame.
Reference: `ItemCacheReceive` (`0x55bdb0`) stores the record, then walks one callback list per record, oldest first, filled by each lookup's miss (`0x55ba30`). A refusal calls each callback with found 0 and frees the list (`0x55bea8`, `0x55bed2`).

Reference: the worldport's teardown timer `0x401bc0` frees every cooldown after the objects' walk (`ClearItemAndSpellCooldowns` `0x6e9ad0` at `0x401c17`). That covers the player's and the pet's lists and the item table, with no flush. Then it cancels every open roll (`CancelAllLootRolls` `0x61b290` at `0x401c2c`), signalling CANCEL_LOOT_ROLL for each one not queued, before the map load.

A worldport tore the old world down inside its packet: the despawn, the world handle and LOGOUT_CANCEL there, then PLAYER_LEAVING_WORLD before the frame's earlier packets' events had fired.
Reference: `SMSG_NEW_WORLD` (`0x401b00`) posts its teardown `0x401bc0` as a zero-delay timer, and a tick runs its timers before its packets. So the next tick:
- zeroes the world handle (LOGOUT_CANCEL);
- walks the objects (`0x467800`);
- sweeps at the local player's turn (`0x5dd543`).
Changed: the packet only posts the load. Three legs at the next frame's start run the connection's half, the sweep and the objects' teardown. The sweep runs ahead of the objects, so the target is still there in PLAYER_LEAVING_WORLD.
