Thanks for letting us know! There's definitely something very weird going on here but I'm having trouble narrowing down exactly what's broken. Can you let me know exactly what options you're picking in the shop (ie, "buy paid services, random user, premium paid account for 6 months") and what happens when you do it? (ie, "I hit 'add to cart' and it doesn't actually add the item to the cart") Right now I can only identify one pathway that's definitely busted (buy paid time, for random user, any item, add to cart: item gets discarded and doesn't go into the cart) and I've tried a number of others that are working for me at least, so if you could let me know exactly what steps you're using and what the actual failure looks like, it will help us figure out what's causing it.
