Bug in initializing levels

[Chrysler]

Hi,

just wanted to report this bug here that happened to me.

Spoiler below!

In the cistern there are three pipes with steam coming out of them. The second and third one is sometimes shut off, but the first one is always open. That makes traversing impossible. According to a walkthrough, it says all three pipes should behave like the second and third one. Took me some time to realize that it's a bug, kept searching for another valve or something.

As others in the forum pointed out, it often helps to reload a saved game where you haven't entered the problematic level yet. This helped here, too. There seems to be a general problem with initializing levels for the first time. IIRC there were similar problems in Penumbra. I'm just interested why that is so and if it could be fixed somehow.
