And it was the first time we see these mobs spawning after playing on a server for more than 2 weeks.

The server's world would get stuck crashing with each reboot so I'm despawning them right now with InControl.

Been having basically this exact same crash but when a mob from the mob attacks the player. Hoping this gets fixed.
