Me and my brother played through grindea and after beating the final boss we realized we missed a catalyst. We got the catalyst and shut it down. Came back a few days later and went to replay the boss and my brother kept crashing me being the host. He was seeing the bosses health bar wasn't moving when we reconnected there were 2 bosses. I finished the boss hoping when we got to the final boss it wouldn't happen but same thing occurred.
