I just played a wave and this weird glitch happened
a robot managed to drop the bomb and we all blew up like ususal but the round reset and there was still a flaming crater where the bomb should be
the robots still tried to bomb it a second time but anytime they got too close they'd die instantly
at one point the tank was about to drop the bomb and it died instantly as well, along with a few other giant robots
it was the strangest match
