Game Crash, not startable again.

Did Ravine with my summoner, pressed Portal, went out, went in again, did not work.
got the error:
"Fatal error in Metadata/Monsters/TerracottaGuardians/TerracottaGuardiansSceptreAmbush_@44: Number of shared states is different on client and server!
delta: 237"

when i log in again, it starts to load into the zone, it keeps happening.

playing summoner with 10 storm mages,1 terra cotta soldier as a spectre, and 1 Cleric.

a friend of mine tried to go in the instance too, with another character and did cras, and cannot use that char now too.

Edit: we were able to recreate the bug.
it happened in groupplay again, after i died, my fried got kicked and could not join, then i revived.
so my guess is that it has something to do with a player dying that has a terracotta soldier as spectre.

best regards
