Sometimes on the Meltdown map in private mode PVP enemy Battleborn will get stuck in a corner and become invincible. Any attempt to attack them simply passes right through them. So far it’s happened twice. The first instances was a Reyna got stuck in the right corner of the moved (2nd) incinerator of the B lane. She kept running in place and was invincible. The 2nd one was Caldarius got stuck in the left corner of the 1st incinerator of the B lane and was also invincible. They both stayed stuck until the end of the match.
