Turns out he, instead of using the TSLPatcher installer, copied and pasted the files into the override folder. Because he did this it caused an NPC I intended to appear in the Entertainment Module appear in the Hangar and break the game. I am certain this will work with the NPC Overhaul mod.
So did you ever find out if this is compatible with NPC Overhaul 1.22? Or do you believe that bug was his own client side issue. Also great mod btw, it will make a fine addition to my collections of upper echelon mods.
