I've been playing with the mods (listed below) and ever since entering some of the train stations, I've noticed some annoying problems. Basically, some of the walls and floors at times are missing, all you have is a dull grey/blue "sky" which if you walk into it, you "fall off the world" and respawn at the nearest map entrance. It's like the curved walls of the station have shifted elsewhere. Is this caused by something in the mods? How can I fix it?

It's Destruction.

had destruction. seemed to increase CTD's for me so i uninstalled it but no graphical anomalies like that. tho i do use FO3 master update which i think helps. and archive invalidation cant hurt

Thank you SO much, that's fixed it. Who knew it'd be so simple? (other than you. )

download and install http://www.fallout3nexus.com/downloads/file.php?id=1904 or the hotfix for correcting these problems.
