Received twice as many crystals as purchased

Just submitted a $4.99 purchase for 55,000 crystals, and now I own 110,000 crystals. Maybe this is on purpose, but I figured it was worth pointing out.

Thanks for reporting. Lucky you :-)

There is a race condition that'll sometimes credit a buyer twice for one purchase. It's not on purpose. (Well, sort of - IIRC I chose this possibility instead of some other possible bugs, like not-delivering-at-all.)

Checked the last few days of purchases and it's pretty rare, so I'm not in a big hurry to fix it - the occasional lucky purchase is okay with me until I find more time for this.
