Okay, after looking through the log... the only remaining advice that I can give is to do the 'Verify file integrity' for the game, AND erase the contents of the \Mods\.modtek\ folder.
Just the folders files and within \Mods\.modtek\, nothing from the \Mods\ folder itself.
If this doesn't fix things? I'd have to refer you to the BattleTech modding discord for a real-time chat session; specifically the #RogueTech channel.
Interestingly,
The newest patch just fixed me, with only a CFC and an install on a fresh game.
Things that make you go hmm!
Thanks again for all your help, gonna go dive in face first now!
