bug or cheats?

Had a game where my backline arty where getting shot as though by a sniper, and then eventually my PAC-3 spontaneously combusts. It had shot previously, but when it died it had not fired for some time.

And the PAC-3 is NOT on the killfeed at match end. Not dying to itself, or anything else. Just boom. Similar thing happened to a small supply dump. No arty, no missiles.

Destruction of the AA was swiftly followed by an airstrike.

Is this a new cheat? I suspect a certain player, but was expecting confirmation at the end.
