Never had this one before. Every time I try to save while in the areas added by OA, the game crashes. It also happens when I try to go into the simulation. This annoying little thing starts out when I get to Baley's Crossroad, or whatever its called. Here is my load order:

Anyone spot something?

FO3 Master Update ?

Huh?

Can you do me a favor and before you go into the simulation turn off your auto saves. Then once your inside Anchorage save normally. Or better yet leave baileys crossing and try another one of the global autosaves. Just as a quick test instead of diving into masterupdate just yet. It isn't quite the cure all everyone says.

I don't use auto saves as they lead to corrupt save games.

Just try the experiment. That will tell us if it a global problem or one specific to that area. Shouldn't take you more then ten minutes.

Try disabling that esp and then try to save.

Thanks for the help guys, but I found the problem. It was EVE, which is surprising cause I already finished OA with it...

Try using GaryBash and esmify eve, that should eliminate the crash. If you have gotten to the point in the main quest where the enclave have created small camps and attack you, then it is likely the plasma thrower can case the game to crash when placed in the wastelands.

That particular crash might be over Achievement 51. Try http://www.fallout3nexus.com/downloads/file.php?id=3813 for that particular crash, although it won't help with whatever else is going on.
