Forum:DLC or Patch glitches

Having an issue here. I just downloaded and installed the gun runners arsenal and the lonesome road and a patch that was required. I havent played in a few months so not sure which patch it is and now when I go in to buildings or the lonesome road it glitches like crazy shows a red diamond with the exclamation point like bethesda games show when there is an object missing and characters NPC and player fall through the floor and crap. It sucks anyone know what the hell I am supposed to do about it? 24.21.147.25 17:37, October 28, 2011 (UTC)
