1. Placed buy order (It didnt show that any was placed, so I spam clicks for about 10-20x)
2. Buy orders finally went through half an hour later, but I cancelled it all without getting any items.
3. No money was refunded.
It would seem that this is a widespread issue, my guildmates are having the same problems.
Thanks
