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`).
- DropItemOnUnit fills the trade or starts one in its call (`0x48da50`, `0x48da62`).
**Changed**
- With a host lent, the 23 movement verbs and Jump apply in the call.
- The autorun bit flips there.
- DropItemOnUnit applies in the call.
- The mouselook verbs still queue.
**Tests:** a press mid-cast cancels before the next line, two toggles in a frame cancel once, and a drop on a player trades in its call.
