Battery Not Dropping After Formarion Cannon,

[Magnulast]

I was doing a raid, with 5 hydroid, and one EV. we were doing well(except for EV not blessing) and we managed to get to the third stage. Of course, since our EV wasn't blessing...we failed the first time, and the cannon reseted the stage, after that we did the first battery I think, and then I killed a enemy and the battery...didn't appear anywhere, it just said it was dispensed/droped....and we wasted 30 minutes searching for the battery ON THE WHOLE ENTIRE MAP nor did the battery ever reset itself...soo we were dead, we allowed them to hack AGAIN and it still wouldn't spawn, then i exited when I WAS SAFE and  the rest were in the down position. I wish i had taken a screenshot however, I didn't. Is anyone else facing this problem?

 

Simplified :battery not droping/reseting after cannon.
