I have installed TTW many times before, this is the first time i have had issues. A lot of meshes got left out when my bsa's were optimized. Does that mean my save needs to be restarted? It is only the "fallout3 - meshes.bsa" that is not normal, so I am assuming it is fine to simply re-install TTW and continue play?
I don't think you need them to answer this question, but here are my specs:
Windows 8, AMD 65-5200 APU, 6GB ram
