I was playing on towny earlier today, then I left for some reason; when I came back, all of my items were gone and I had starter items. IGN: snoch this has also happend to my friend mcquade54.
There was a rollback of several days. I hope this has fixed the problem. I think the rollback was like 4 days or something like that. If this hasn't fixed the issue, please send a report with proof to [email protected] in case they decide to do a refund.
