I had my name set in normal letters and it reset it, this is the second time its done this and the first time i had used different characters (but ive always used special character it was the first time it had reset out of the blue), i tried using normal text and it reset again and i have no idea why, is there anyway i can fix this please its happened twice in a row and its very frustrating to not know what im doing wrong.
