It seems OM is designed for turm upgrades only for types VIIC, IXB, IXC (as stated by Lurker in his original thread)
The new version of my mod is in good way.
Dark Waters is about to be released soon, and many things have changed (but not the upgrade problem unfortunately)
Once released, I’ll ask to close this thread because it will not be supported longer, and Dark Waters will have it’s own thread.
Keep on station
