Hey linkesauge,
Don't know if this has been reported or not but there are two files that have filenames that are causing the FOMM package manager to go bellyup and cry,
1) Textures\CGC\interface\icons\pipboyimages\weapons\M79.dds (in main files part1)
2) meshes\CGC\projectiles\M79casing.nif (in main files part2)
Ditto this. Are those names intentional? I could possibly add support for them in fomm, but both of the decompression programs I have here that can cope with multi-volume rar archives are blowing up on those two files before I even get as far as trying to make a fomod out of them. :unsure:
Edit2: On closer inspection it seems to be sharpziplib that's causing the problem in fomm, and not fomm itself, so it's not something I can fix. Hopefully they aren't intentional...
