At some point in recent updates fire beetles started causing their explosion damage also if destroyed rather than detonated. As a result I had some games where a transport hovering over the ACU was killed by the flak and the beetles killed the ACU in return, and one where more hilariously, an ACU OCed the beetles and they ended up killing him.
I can't deny it's a LOT of fun blowing people up right now, but it surely invites discussion.
