When playing with aliens (Just checking em out) I noticed when you put alien armor on your Shevaar it makes them invisible on you assign soldiers, Hire/Fire employees, equip soldiers, and in the mission they are purple boxes with the gun sticking out. Whenever you click on them or when the mission starts, it says can't find 'aliens/shevaarmedium/head01'
I am sorry if this has already been brought up but I couldn't find any other topic on it and I wanted to bring it to your attention.
AWESOME GAME BTW!!!
