I can't seem to enter the Cash Shop without the game client crashing entirely. Weird thing is, this only happens on my thief. My other characters can enter the cash shop just fine. My thief's name is "knifebabe". I've attempted to enter the Cash Shop around 6 times, and it simply won't let me in. Edit: Okay after like 10 attempts the issue seems to have resolved itself. Will update if it happens again.
Regarding the cash shop, i only know of a situation where sometimes after being inside the cashshop for 2-3mins, the client crashes
The fix for this for 99% of the cases is just to restart your computer. Do not hard reset (turn off and turn on), be sure to press the Restart button in the menu instead.
