Client Crash while casting with many Soul Eater Stacks

Hey there, every time i get Soul Eater through Headhunter and my Casting speed becomes very fast my game crashes and sents me to desktop. Upon starting the game my Inventory is empty, EVERY item i picked up in the map is gone and my Portals are deleted aswell. This happens on my Soulrend Trickster with EB. I could reproduce this crash 4 times already.
