Haha, I'm pathetic ;_;
I wonder why it says that when I try to login to the lodestone.
The same thing happens to me but I was able to find my character just fine on there using the search tool, so he still exists.
I thought that I was perhaps using the wrong account, but, I did a password reset with the only email I actually use and then successfully logged in with the new password + account I thought was correct, so, that has to be my account. Not sure why it's telling me I don't have any characters. Unless you can have multiple accounts tied to 1 email or something....
To be honest though I just assumed it's because I haven't logged in for about a year now, I didn't really play in the last few months or anything.
