It is possible to get stuck in timed circle in Castle Basement

[Arcanister]

There is a timed switch, then ladder made of falling blocks, which then leads to pool with conveyor belt above a pool. If you go through this sequence for second time, the elevator will stay up and the door will close behind Edgar, making game unwinnable.

My suggestion is to make the timed switch on the bottom both open the door and summon the elevator down, to make it possible to go through this sequence again.

I think I know where you mean. I'll look into this, but for the moment you can just reload your last save.
