I have modified the human to use a default sound set, and removed the race designation tags on the names in each UTC for those characters, and I have updated the Korriban and Dxun tombs with improved loot. I have also modified the names of the loot drops to accommodate the items included in a proper way for immersion. Azkul got great new unique armor, Dxun/Korriban have been successfully altered, and the space suit mercenary skins on Onderon have been improved.
NPC Overhaul should be totally compatible with 2.0.8b now, but please save often and in different slots like the game suggests so you can avoid an unexpected conflict. 2.0.8b can be installed if you already have 2.0.7b installed, it will patch and update the content. I don't know much about the language problems in the game. The item descriptions need to be entered into the TLK file, with translations. There also may be a way around that, so I will keep looking for ways to address this issue, but I can't promise anything in the short term.
