Summary of bug here.
Steps to Reproduce
Go to any accessory page, and purchase an accessory. Without closing the menu or going back, purchase a second accessory immediately afterward, and it will remain locked. Before it updates, you can purchase the locked accessory twice, paying double for one accessory.
What I expected to happen
I expected an instant unlock or for the second transaction to not go through while the server updated, but it took my funds again anyways.
What happened
When purchasing new accessories, purchasing two or more at a time quickly will cause the second accessory to remain locked after purchasing. If you try to purchase it again, it will allow you to pay twice for that second accessory, paying double what it costs.
