I have received duplicate purchase notices at least four times today and yesterday when the purchase has been successful. The few times I did not realise it was successful so I went back to the last page and purchased again ending up with two items. This third time I have caught on and am not going back!

It has happened at...

Five Seven Five Zombie Den Recycle Beast shop

Recycle beast was most recent and I looked at the url "https://subeta.net/ss.php/recycle/buy_success/218635". It even says it is a success despite getting the message.

I had that problem at Esther's.

Happened to me a few times in quest shops yesterday as well

It's been happening to me on at least 50% of the items I purchase from special currency shops since they changed them to add that message and whatever else they did that made Ctrl+clicking not work in Firefox

I have only noticed it since the downtime but maybe this has been a long term problem.

I have these problems, too. I saw that error message several times. I got duplicates from the cash shop two times today while there was lots of lag. It seems like the error message didn't display when this happened.

I left the site for a while to do some cleaning. I'm back on, and the lag seems a bit better now. I purchased two more items from the cash shop and I didn't get anymore duplicates.

I am using Firefox.

I did make a couple but they weren't terribly expensive so I wasn't too bothered, plus I can't remember them now ^_^;

Same here. Just a few plushies for me from a quest shop that I tossed into my shop.

You said you bought duplicates from the Cash Shop though <3 (Sorry if you already saw Destiny's Post or already filed a ticket... just wanted to make sure <3 )

I saw and filed a ticket. Thank you, though! :)

*Edited because I made another grammar mistake. Whoops!
