@Astek:
Quote: "As long as I had not encountered the door that needs the spanner to be opened, I could not enter the room containing the spanner. I could open the door to the storeroom and see the spanner on the shelf, but not actually enter the room until I had clicked the jammed door. Loading an early savegame reproduced the bug but I have to try again from the complete start if I encounter the bug again if I do the door in the "wrong" order."
I tested again and I have to admit the bug was only in my savegame. Since the game goes very fast up to this point I tried to reproduce the bug by playing several times from the start but it wouldn't show up again
But I ran into another problem (starting from a saved game in the generator room) in the 2nd level. Inside the armory is a door that "requires an officers key". So far I found 1 key in each level which allready served their purpose but I cannot find another one in the 2nd level. Did I miss something or has loading the savegame destroyed some variables? (if its a spoiler please send me an email where to find the "officers key")
In case you find my grammar and spelling weird ---> native German speaker ^^
