Dont know if its just me or something im doing wrong but when I place a group in the editor and try to make one of them as the player it comes up as bluefor marine. But thanks for an impressive set of units.
Narrowed it down to the Assault Rifleman and the Heavy Gunner, I went through all the units under ACE/Special Forces and those were the only units to crash the game. I even tried placing a group in the editor and took out the Heavy Gunner and there were no problems
