Fallout 3 crashes after leaving Meresti Trainyard

[Alexmunst]

After I leave Meresti Trainyard during and after Blood Ties I can quick save, save or fast travel once, and then if I try to do one of those again it CTDs. I've tried killing my character and it still CTDs. Any help would be appreciated!

Try removing the unofficial fallout 3 patch. I've had/heard of crashing issues with that when entering/leaving Megaton. Otherwise, you may have to remove blocks of your mods until the game works again and then add them back one at a time to figure out the culprit.

I found out that the problem was caused by Firefly Ranch. I wasn't able to find anything wrong upon looking at it in FO3Edit, so I simply uninstalled it.

 

However, I did find that it changed Meresti Trainyard in some way. I'm not capable of fixing something like this, so if someone wants to look at this, something in Meresti Trainyard was modified and was causing the bug.

With a thing like that, you might just find that if you loaded Firefly Ranch without some other mod, there would be no crash. The problem is probably a conflict with FR & another mod which to figure out without being the mod author is like finding the proverbial needle in the haystack. If you unload all your mods and only run vanilla fallout 3 and firefly ranch AND there is still a crash at Meresti, then the problem would be specific to FR and a fix is within reason. Otherwise the permutations of possible conflicts is far too massive for a non mod author (in my opinion anyway). It's hard enough to figure out conflicts with other mods when you are the author yourself.
