"As part of our continuing effort to combat gold spammers, botters and exploiters, we recently banned a number of accounts," the studio posted. "After several players appealed, we were able to investigate the matter further and discovered some legitimate accounts got caught up in the sweep. We unbanned accounts last night, and have email responses going out for those affected from our support group. It is never our intention for legitimate players to be harmed as we work to keep your game free of cheaters, and we sincerely apologize for the mistake."
ZeniMax also said that this past week's maintenance accidentally deleted some characters' bank expansions and the items held inside of them. The studio put up a process how to regain those slots and items if it happened to you.
