[in-game shop] Game freezes everytime you buy an item
Steps to reproduce: Click to buy an item from in game store. Game then locks up for 2-4 seconds. Must click to buy again as first attempt didn't work. This time with no freezing. How long has this been happening: Since at least 4.20 Frequency: 10/10 Steps taken to fix client side: Reboot, repair, reinstall. (all with no effect) System specs: CPU 3.5GHz; RAM 8; GPU Radeon 6650; Win 8.1.
Edit: I should also add that this doesn't happen to subsequent buys while the store window is still open, just the first buy. If I close the store and reopen, then it will happen again.
This happening to anyone else?
