Boss dissapears instead of dying - battle never finish.
1. I encountered this issue on Xbox One X
2. I was playing with friends
3. I was playing as Catti-Brie
When Kronus Seven Scars got to close to gate behind him his health bar disappeared and reappeared after he get closer to the middle of area. After defeat he fell on the ground and disappeared but the battle was not finished. The encounter music was still playing but nothing more. There was no enemies. Taunt ability and aoe skill around area where he disappeared did nothing. Only option to leave finish was to return to menu and lost all rewards and progress.
Boss instead of dying dissapears and battle never finishes leaving players trapped in the area without options to finish the act.
Death of a boss, act finish, rewards distribution.
