Reset temple

Just start your build and lock the room before the ones you want to get rid of. Obviously don’t loop. Imo it’s not that big of a deal to do that and even move the architect as you go

Before you get the snake going I'd suggest boxing in the architect and forcing it to spawn in the block where the last depot is. This is the ideal spot. Everywhere you see red are the tiles you want to fill with rooms then run architect.
