Fatal error in metadata

The game crashes, and I cannot log in with the character for 15 minutes.
Are you kidding me, GGG?
This bug is there at the beginning of the 0.2 patch...
Can you fix it?!

Exception
Fata error in Metadata/Monster/SkeletalKnight/SkeletalKnight@36: Number of shared states is different on client and server! Delta: 143
