Bot/AI thinks you are dead and tries to revive you while alive.

Recreation: Be knocked down, and give up. But right at the moment you are about to succeed in giving up, an ally revives you.

This, possibly with the aid of lag, causes the bots to think you are in need of a revive. A bot will be dispatched to you and if you are moving will stagger-move toward you while rapidly switching between paddles and primary. If you stand still the bot will deliver a charged paddle, then wander off. Only for the same bot or perhaps whichever bot is nearest to repeat. This will happen until you die.

(Selected PC and Steam as tags but "AI Logic" would seem most apt.)
