===Object Number Gotchas===

*When objects are despawned, you can't change their number (likely because action target filters generally don't return objects that aren't on the map)
*Number Check scripts for the object number will trigger while the object is despawned, usually on the game tick after the object is despawned
*Message, Power, Multi, and Global/Player/Team Number Check scripts will be triggered while an object is despawned, assuming Always Run is ON (Note: Team Number Checks don't seem to trigger if the script owner is despawned)
*Object numbers are saved while the object is despawned, so when it's respawned the number will be the same as before
*Object numbers are saved between rounds
*Most, if not all, properties that are set in the Properties Window are reset to their original values when the object is respawned
*An object's Number is available for reading and writing after calling Spawn, but Despawn makes it inaccessible again. This works even during the same game tick.
*Basically, for a despawned object, you can call Spawn, use its Number, and then call Despawn during the same game tick and the object won't spawn or trigger its Spawned condition, but the Despawned condition will trigger
