Need help, error #134

So I was in a dungeon on the Frostmourne server and we got wiped and as soon as I pressed "Release spirit" the game crashed and it showed an error message that says: "This application has encountered a critical error:

ERROR #134 (0x85100086) Fatal Condition

Failed to read file
WORLDGENERICPASSIVEDOODADSTREASUREPILESGOLDPILEBAS E01.blp."

I tried deleting the cache and wtf folder and nothing helps.

From the website go into My Account>Services>Select Realm>Select Character>Set Currency:Free>Character Unstuck

Okay, but will that solve the problem? Will I always have to do that when i die?
