So unfortunately, the problem persists.

Thank you very much! I'll try today. I hope I don't delete active characters ...

I apologize for the English, but I thought you were a Czech company.

No. The problem is that I can't change the server for a character I haven't played with.
Example:
I have two characters: "A" and "B". "A" is on server "X" and I played it last.
"B" is on server "Y" and I would like to play on server "Z".
If I change the server for character "B", it automatically moves the character "A" to that server. So if Server "Y" stops working, I will have a character "B" in my menu that cannot be connected or changed server. It doesn't matter if it's an official or community server.

In practice, this means I can't play two characters on two different servers.

You don't understand me. I'll try it in English ...
I want to create a new character on a new server. The problem is that instead of creating a new character, the last character played moves to the server I chose for the new character.
