Missing Valve

[Thomas]

VampLena:
Note that this only applies the the Cistern map (the level with the valves and water) and NOT Cistern Entrance. Unless you have run in and out of that map 10 times or so, there must be save games from before you first entered. Check "Load Game" in main menu.

Zanderat:
As Jens says, it is a problem that arises when loading a save game made with version 1.0 in the 1.0.1 game version. I am afraid it is not much we can do about it.
