So sorry! I try to get to bug things when some sort of fix is thought of.

I'll check the method for changing username, but there's no way for it to not allow you to change it without giving you some sort of error message (https://swmff.github.io/rainbeam/src/authbeam/database.rs.html#1002-1062).

Does it say anything on the page after you attempt to change it, or does it go through and then just not properly change?
