Instance Bug since Patch

Hello There,

since the Update yesterday i have a very frustrating problem with the game. 3 from 5 maps crashes when i open or i port out in my hideout. Every Time it shows me "Instance cant Load" then kicked me out to main menu, when i reconect it works. But 5 min later new map its again. Its very frustraiting. I dont have time to log in 200 times a day. Yes i have all new driver Updates, I have a high end setup thats not the problem.
