Shared states fatal error

Was running maps, was currently running the Crypt. I was killed and a second or so after my game crashed to desktop with the error:

"Fatal error in Metadata/Monsters/SkeletonGolemancer@36: Number of shared states is different on client and server! Delta: 115"

Basically locked my character out of the game until it kicked me out map that was causing the issue. Even starting a new map on a different character didn't resolve it. Was forced to wait until the instance closed.
