Boss companion crashes game as soon as I login

Crash report says:

"

Fatal error in Metadata/Monsters/ChaosGodOwlBoss/IcyOwlBossMinion2@38: Number of shared states is different on client and server! Delta: 210

My game crashed upon my companion attacking something. Can't login anymore into this character since.

Companion got 3 Rare Mods on it:

- Extra Cold Damage
- Cold Resistance
- Conjures Flame Walls

Hope it helps for fixing this asap so I can login again.


Edit: After getting thrown back into my hideout, probably because of elapsed time, I can login again. The map i went into was the Quest Breach Boss encounter of Tul and Esh.
