Hey @ Firthunands91,Ey @flammy` what about I told you in #95 ? Any way to fix it? I'm almost sure you can play 2x2 Copters.
Sorry man I completely missed your post!
You are right, it should be possible to pick 2x2 Attack Copters.
I just fixed this in version 0.972. You will have to remove your existing copter units and create new ones, the fixes only affect newly created units.
