When trying to make the realm name italic using §o, I saved the name after I had filled in the text to be italic. Then it came up with the screen saying "saving realm" so I expected that the name to be saved. When I looked at the name in the edit screen again it just said "§o" so I deleted it and tried again. It never saved so I have a blank realm name now.

When looking at the image with "Realm" after §o note that in the top left corner of the screen it says: edit "" . It usually follows the text in the edit name box so the bug is about the § symbol not it saving.
