This happened to me also. I have no clue what's going on.
"This character has been renamed [Alleviator Luminaria].
* Former name: Alleviator Luminaria"
It says it's been changed but it's not changed and I didn't do it. It also says I joined all of my linkshells and my free company today, but I've been a member of all of them for quite some time now. I noticed two others in my FC have had the same thing happen to them.
