Hi,
When did you created your account?
Remember that last 2017 May 5th there was a wipe.
If there was a deletion but I think the accounts weren't completely deleted, just the characters, you may have forgotten the account or been banned
(If it is neither of the two things, it is possible that Dierufei is right, they will have deleted your account using wipe)
Yes that probably what happend. Team leader says the same. thanks anyway!
