Apposso

Hey, I have transfered my elysium and nost chars, both had an "Apposso" and I deleted the nost Apposso, and also before I deleted the nost Apposso. it wanted me to rename the elysium one because it "violates naming rules", but that doesnt make sense as Apposso is a normal name. Its the same actually with all my elysium names, I have to rename them, But its very important for me to call myself that. Also worth mentioning, I was able to add with another char all the chars in my character screen with the elysium chars, as friends. So could it be that they count as existing chars, even though theyre flagged for rename? Anyway, Id appretiate some help because calling myself that is important for me. Update; I called myself "Willapposso", and tried to add "Apposso" and it says "You cant put yourself on your friend's list". So obviously theres an error in the databse with the names or something.

Thank you for the advice, random citizen, appretiate it.
