Hello, I was wondering if you could help me. I have a slight problem with my KoTOR 2 but i'm not sure if it's the USM that's the culprit. I'm using quite a few mods besides this one you see. I've just found the 1st workbench on Peragus and I found that the only thing I could upgrade at that point was my armour (minor uniform); none of my weapons appeared in the upgrade list. Any ideas as to what's caused this? If if helps, as well as USM, I'm using the TSL Restored Content mod v1.4, TSL Un-restored Content (final), High Level Force Powers + Improved AI, Prestige Class Item Pack, Jedi Temple (+ expansion) and Kreia's Assorted Robes. Thank you.
