This bug hasn't been documentated - and I haven't gotten around to fixing it due to forgetting it exists. But...
If a player uses /normal and then their account gets saved by a multitude of other commands and happenings then their rank is overrided and set to donator.
This happens because /normal sets your rank to Donator but doesn't save it. Some commands and listeners save the player but doesn't recognise the player as in normal mode thus overrides. This means even if they reconnect they lose their rank and it has to be reinstated by someone with access to the database.
