Bug: npc_personality_core animations revert to default pose state for one tick

[pivotman319-owo]

Describe the bug

Recent tick calculation changes from within the engine have caused scripted idle sequences for personality cores to break slightly; after a vcd is done playing, personality cores may revert to sphere_idle_default for one tick before returning to the intended animation as called by SetIdleSequence()
