Summoning Avatar Crashes Server

Game mode: [Online | Private Server]
Problem: Crash
Region: [NA]

We were doing a storyline and tried to summon Set in the arena. It immediately crashed the whole server upon the summon. we did it with other Avatars with the same result. We summoned Derketo last week, so we know it works on the server, but todays patch broke the Avatars…

Steps on how to reproduce issue:

  1. Summon an Avatar
  2. Watch Server Crash.
