Hey there, thanks for the info <3
Unfortunately, I am still not able to reproduce this bug

I recorded a short clip of my attempts in both firefox and chrome::
As you can see in the clip, the only way I am able to get the username to reset in any way, is if I change it to something, then click the (i) to open the credits info, when you go back the name resets to whatever it was before (but not specifically 'username')
I am also considering this as a bug (credits button) as the name input box specifically sets the username when the name input window is deactivated in any way:
So yea, I'm going to investigate the credits info bug as its the only one I'm actually able to replicate lol. The next version will also handle the auto loading of save data slightly differently (which may have fixed the credits bug already lol)
Anyway yea... Thanks for the info. I've added steps to replicate your bug report to the description of my video as well in case anyone else watches it and is able to replicate it
I've also had other folks test and no one else is able to get the same bug :/
