So on the regular Reunion Mo Incarnate Trial run last night, we had an incident where the teams reshuffled and we somehow ended up with 9 players in team 3. Now, this would probably be very ideal conditions if we had brought along a WS/PB but it somehow didn't seem like intended behavior.
It looks like the issue comes from the original leader of team 3 (Sacred Rose) joining after Muleta from team 2 was moved to team 3. As the leader, Sacred's spot was reserved so she was forced in the team even after a late join, despite it already being full. Muleta is swapped at [1:05] and Sacred rejoins as leader at [1:12] resulting in the team of 9.
Another unrelated issue that is also part of the video, is a huge drop in fps around the time Nega-Pendragon is close to death. Starting at [7:50] and continuing for about 40 seconds, we all collectively experienced a mega fps drop (0.39 fps as the lowest according to the in-game counter). Something always likes to cause lag in that fight, but it seemed that it was greatly increased this time around. Likely the army of Lores?
