I did a name change for personal reasons. But, the reason why I did a name change is beside the point.

The important part is that when a name change is completed, it is expected to work in a certain manner. Legacy players or legacy server players, that do a name change for any reason at all, will run the same risk of encountering this fatal error that I did.

I do not wish for this to happen to anyone. It is not a good feeling.
