I was trying to fight Kaji with Momadt and PoofyTheWeeb, but Kaji not only spawned once, but twice in the same fight. We had one in Oni mode and one normal one. Then when the oni mode one despawned in seconds, the normal kaji that we had went oni mode, after we started to kill it. We managed to get that one down to Purge Domain, but the second it teleported back to the middle it despawned. Any idea why?
