I purchased some mainland and was standing around for a good 15 minutes when the sim crashed. When the sim came back up, the land I purchased was still owned by the previous owner. I've already paid for the land once, it shows in my transaction history. I shouldn't have to pay twice. I do have a ticket filed with LL, but as usual, they don't like responding very quickly. Has anyone else experienced anything like this? If so, What happened in your case?
