Cassian vs. GLAT = missing buttons

I spend on this game and expect that my purchase should wai. I unlocked 7* Cassian day 1 and upgraded him to r10 and the rest of the rebel fighters to r9. He is a hard counter to GLAT, but several times now I have lost buttons. It seems to happen if GLAT dies before Ezra, but idk if that’s the reason. It has cost me in GAC, which is the only game mode that keeps me playing. This is a brand new, expensive squad. If I bought this at a store and it malfunctioned like this, I would ask for a refund. It is unacceptable that CG allows this to happen.
