Hi!
I've got 2 CH-48 Charlie's (lets name them A and B) in one base. The second one(B) was originally bought in another base - equipping and assigning soldiers was without problems. After some time I transfered charlie B to my "capital" base. When Ufo appeared, I've sent A(containing 6 soldiers and a Hunter Car) to terror site, and tried to equip soldiers in B for landed ufo. But I could only assign 3 soldiers to B. I tried to reload game, and nothing changed.
