It might have been the inactivity cleanup. https://forum.warmane.com/showthread.php?t=474191

I think it's a bug, because people keep complaining about it. In inactivity cleanups people lose their names and are forced to rename to continue playing, but in this case they are keeping their names and they are still being asked to rename.

In inactivity cleanup your char is automatically renamed. I got 2 chars renamed and one of them is "C_10009200".
So it is a bug for sure. Happened to me aswell. Wrote a ticked and the GM answered it is not his job. So next step is God I think.
