Bought an item - Clicked on another item to get it and the timer said 10 second. Refreshed said 13. Counted to 13 said 4. Counted to four said 7.

I think it works that way to stop autobuyers, so I don't think it's broken. I always give it an extra thirty seconds. Yeah, I might lose the item, but fucking with it by trying to count exactly gets the same risk of loss, for me.

So I tested this out (set a time) and it seems that if you refresh on the item it will say you have to wait longer, but if you go back to the shop and click on it from there it will allow you to purchase it.

I had refreshed after the time and it told me I had 34 seconds left, but I went back to the shop and tried to buy it and it let me.

So, I think this is intentionally as Solsticesprite mentioned.

Well that is really irritating if it is intentional. But ok - Go ahead and lock this
