The frame applied its packets before its input. An `OnClick` reading a unit saw what this frame's packets wrote, and a world click on a unit despawned in the same frame missed it.
1.12.1's tick runs every window input record (`0x423920` at `0x420d23`) before the packets (`0x420d55`). The mouse turn (`0x514400`), right-click interact and cast (`0x514b70` → `0x481f60`) and the press handoff run inside the record. Frame-time work, like the controller's movement and the leash (`0x4818c0`), comes after the packets.
The UI input pass, its bindings, the world mouse and the look sampling, and the world clicks now run ahead of the net drain. Then a new resume point, the feeds, the `OnUpdate` tick and the controller's step run after it.
Tests: a click reads the unit before its frame's packet, a click selects a unit its frame's packet removes, and the pointer edge.
