Best way to separate Pals into designated zones?

Hello! We're currently working on a multi-level skybase, and while it's been an exciting project, it's becoming quite chaotic with Pals freely roaming between floors.

We've been trying to organize them into dedicated zones — each with food, workstations, and sleeping areas — Every zone is fully enclosed with walls and intentionally built without any doors or windows, to prevent wandering.

However, despite being completely sealed off, some Pals still manage to teleport out of their zones after a while, and we’re not quite sure why this happens.

Has anyone found a reliable way to keep Pals confined to specific areas without them wandering off or glitching through boundaries?

Thanks in advance for any tips or suggestions!
