I looked into the rivet city crash problem. Based on the topics I've seen revolving around this particular game error, none of them have mentioned the fallout 3 unofficial patch. I thought about what mods could possably change game settings that would cause a clash in the console? Of course, the patch. It appears that the Broken Steel branch of the patch was,indeed, the corrupted instigator of the Rivet City console crash. I'm not exactly sure what in this branch of the mod changes, but I know for a fact that this was the cause of my rivet city crash problems. If anyone is using this patch and is having crashes throughout the capital wasteland, resort to this topic. This could save you a lot of time.
