Iron Citadel, checkpoint

Had a Waystone with a couple revives, died once, was sent back to last checkpoint, wasn't on Boss fight. Instance did not render properly, bug reference# 2,936,940,475. Could not move in instance, could not reset, restarted POE2, swapped characters, verified files, reverted my graphics settings to low, restarted a couple more times, invited another player(they had same issues). Citadel failed.
