wierd character display glitch

Describe the problem. Be as specific as possible!:
log in using the main site to launch your client and be instantly logged in on your main account and able to choose a server
click on any server, go to create a char
click go back, the button on the bottom left, to get pushed back to the login screen

login with a different account
first accounts characters are still visible


i wasn't sure if i logged in with the right account, i logged out and logged back in multiple times but it still showed my main account's characters.

i didn't try to log in on any of the characters because i knew this was abnormal client behavior, but still.


what the hell could even cause something like this?

edit: FFFF, I SPELLED A WORD IN MY TITLE WRONG, DANGIT I BEFORE E EXCEPT AFTER C, YOU THROW ME OFF SO MANY TIMES.
