Frequent pet bug - Disconnect me till map run out

Here is the bug, playing as huntress with big monkey as pet : "Fatal error in Metadata/Monsters/Quadrilla/QuadrillaBossMinion2@56:Number of shared states is different on client and server!
Delta : 52

It is really boring because everytime it force me to disconnect for 5-10 minutes and break my map.

I find this interesting as I'm playing huntress with silverfist tamed and I am getting crashes. I am going to try to run a few levels without him equipped and see if that is more stable. I recognize this error you're getting too. I had to wait about half an hour before I could log in again.
