It started during pekaboo. Whenever I clicked on an item to buy it, it would instantly buy at least 2, sometimes 3 copies of that item. Now I didn't particularly mind then, because they are limited items and I'm a collector. But... I did end up wasting about three times as much money on pekaboo than I intended because of that.

Anyway, turns out it's not limited just to pekaboo. buying from official stores and the shop search is fine, but, say... if I have 10 quest points and I try to buy one 5qp item, it ends up buying it twice instantly, leaving me with 0qp. If I have 9qp and I try to buy one 5qp item, it just buys the one copy and doesn't tell my I don't have enough for another. It behaves normally is what I mean. It gives no indication that it is trying to buy another.

I've also encountered this problem in Esther's shop. I am running very low on tokens now because I ended up spending three times as much as I meant to. It's very bothersome. This problem only occurs on Google Chrome. It persists even after wiping my cookies & other history.
