So, I just installed the mod today, and went to purchase a new mothership...
Well, all the upgrade spots are gone and there is a big red sign in Russian that I would assume says there is an error. I tried almost all the motherships, and this message only appears for the "Other Models" section, but all but three of them give me this problem...
I've included a screen for details. I tried searching in this thread for an answer, but maybe I'm the only one experiencing the problem...
Ships That Have Error:
Alien dreadnought
Alien frigate
Chimera
Super chimera
Phoenix
Portal transport
Stone Arrow
Angorian Frigate
Ships That Work Fine:
Silver Arrow
Ramadanta
Star Hammer
