Password resets every time

Ever since this migration happened, when I try to log into my account, my password is not accepted and I need to reset it. I always reset it to the same password. The next time I go to log in, my password resets again.

This has happened maybe 10 times in the last couple of days. Am I the only person with this problem? Is there any fix? Seems like a really big bug.

I'm sending you a PM, with your help I could fix this in the weekend or even right now.

There are some more people who have this, but only a very few. I can't seem to get a way to reproduce it, so I hope you can work with me over PM a bit.

Alright, logging in with emailaddress instead of username works as well now
