Customers intermittently walk back into the building during exit.

What we know:

• Intermittent (not every NPC, not every exit)
• NPC walks down to stair base, then back up and into the room center
• Happens with the player outside the building
• Started in 2.0.0

Needs investigating:

• What's re-sending the NPC to an interior position after RecallNPC/ReleaseNPC
• Whether a second player being inside affects it (FindPlayerInside is MP-aware)

ReleaseNPC leaves stale CurrentDestination. When PendingExteriorDestination and SavedChasePosition are both null, it sets HasDestination = true via reflection but never calls SetDestination. CurrentDestination stays at whatever the previous EndSetDestination wrote (usually Vector3.zero). NPCMovement.UpdateDestination then re-fires SetDestination((0,0,0)) every FixedUpdate.

IsInsideBuilding misclassifies nearby exterior points. It checks only the local-space XZ rectangle (0 ≤ x ≤ roomSize.x, 0 ≤ z ≤ roomSize.z) with no Y bound and no wall/collider test. Any physically-outside point whose local coords fall within the room rect (e.g. a spawn point a couple meters past the door) gets classified as "inside," so the SetDestination prefix re-intercepts it and routes the NPC back through the doorway.

I have patched this in OTC and confirmed it does work.
