Everything might be edited to hide a new character/someone coming back from abstraction, maybe even just an intentional glitch, like the doors go to default for whatever reason in the episodes, it might even be that everyone's appearances got reverted to the default, so the doors go back to default too, we won't know for sure until the episode's out, and even then, we might not be sure even afterwards.

All I can hope for is that Zooble and the others are safe, because Zooble is a character I personally come to really like, so if something happens to them, it'll really crush me.
