Hi, i'm currently using the unique tame beast skill from the new spirit walker ascendancy but i've been continuously crashing as i try to load up that character and get the message: "Fatal error in Metadata/Monsters/Quadrilla/QuadrillaBossMinion2@44: Number of shared states is different on client and server! Delta: 172" My game only crashes when I load that character up. My ingame character is called KeeperKeyes and any help with this would be greatly appreciated.

Update: after verifying files it didnt fix but it did after leaving it for the map instance to end has fixed

I have the same problem... bUT SINCE 30min and still not fixed : I did lunch with the possibility to go in town. It worked
