A bug I reported went live - this is a PSA
When purchasing chests + keys in bulk, do NOT click more than once on the "unlock" button in rapid succession. You will be charged for and receive more chests than you want.
If you click too many times and too fast, which might happen if your finger is a little twitchy... You can purchase a WHOLE lot, and the numbers will NOT match what you intended to buy. On the PBE, I was able to get 140 chests and 100 keys at once, and if you're thinking "those numbers don't match though!" well, you're right, it's a bug, and you don't want to test your luck with it.
Be very careful not to purchase more than one at the same time. It's a bug, it will need to be fixed, save your wallet.
