It has been brought to my attention that when buying the "instant shipping" special with game coins, the shipments which were already being processed weren't finished instantly and still had to wait for process.

I have resolved this issue, causing previous shipments to finish instantly as well.

Ironically, by fixing this bug there was a temporary glitch giving ALL players instant shipping for the past few hours. It took a while for you sneaky guys to report this to me haha. Anyway this glitch has been solved. Thanks to Triad for reporting this glitch.
