When I purchased from my cart in the cash shop, after I clicked on the purchase button, it took me to a page with this error message:

Fatal error: Call to undefined method Queue::addToQueue() in /www/subeta.net/cashshop.php on line 1454

The item I purchased is in my inventory, so I don't need anything, but I thought you would want to know about the error. Thanks!

Edit: I just went back to the cash shop and the item I'd bought before was still sitting in my cart. I removed it and bought more items, and I would get the same error messages as above, they would show up in my inventory, but still remain in my cart. Thanks!

I just checked it, and it seems to be fine now! :)
