Fatal Error preventing me from playing one of the character.

I have encountered an issue entering the game my new Lich character. This message pops up everytime I tried to enter gameplay:

Fatal error in Metadata/Monsters/RocksliderSpectre@26: Number of shared statesis different on client and server! Delta:134

It seems it has something to do with the new Spectre Gem, please fix this ASAP.

I have the same problem with the Swarm Host tame beast skill gem. After changing locations it's not allowing me to login onto the character.

Same problem and no fix....
