In Fallout 3 Game of the Year Edition (via Steam) I have the red exclamation marks (mesh placeholders) in the Germantown police station and in the Anchorage DLC outcast base (where the outcast guys fight the mutys). I do not have any mods installed. Any help I could find on the internets talks about interfering mods, but I not have any. I also reinstalled the whole game, but it did not help at all. Any ideas?
It's even worse. In Germantown one muty seems to be missing on the lower floors. He is insulting me and I can see his Chinese rifle inside the placeholder. I could live with that, but when I enter the basement Fallout 3 crashes every time, so I guess there is even more missing.
I reinstalled again, but to no avail...
I started a new run to check if the problem is part of the saved game, but the problem occurs already in Springvale. I now remember seeing those red objects inside he house at the street crossing (the one with the suitcase at the entrance). Since only the top of the red thingies is visible in this case I did not recognize them as exclamation marks back when I started the last run.
I played my first runs with the stand alone (boxed) version of F3 (the one with Lunch Box and Bobble Head) + boxed Point Lookout and boxed Broken Steel. Since it was cheaper to purchase the complete GotY Edition on Steam than to buy the missing DLCs separately, I uninstalled and reinstalled from Steam. I did not have this problems with the boxed version. Neither cache verification nor reinstallation solve the problem. I don't care if I cannot play some minor side quests, but I do not accept if a complete DLC cannot be played (the Outcast Outpost near Baileys Crossroads is just a hole in the ground with some floating exclamation marks).
BTW: I installed the game on a different machine but it has the same problems (Machine 1: Athlon 64 5000+, GeForce GT 9500, W7-64; Machine 2: T9600 2.8, Quadro FX 3700M, W7-32).
Another thought: Could this be a Windows 7 Problem? Should I try a XP machine?
We are getting closer: The exclamation marks vanish (at least in Springvale and Germantown, can't check at the Outcast Outpost) if I am disabling Broken Steel. No idea why. I will try to fiddle with the loading order tomorrow...
