Hi, yesterday I recived an offer on a Lot on TP but when I clicked "Accept" the page doesn't refresh. So I went to the trading post main, clicked on the offer on the lot but it says that I already accepted it, but I haven't recived anything from the offer. The man who made the offer said me that he hadn't recived back his money. How can I solve?
