Website character tab frozen

[Riran]

Hello my main account is named Riran. I was making a huge amount of characters to see how many you could have at the website and after a giant amount of characters that i made my character tab froze, but i can still access my Riran character which is the one i play on. I would like to know if someone could somehow fix that or delete all of the characters i created except for Riran. I have tried refreshing the page, clearing the cache and all history, and logging in and out.
