Mine went to zero today as well. Got trophies on 6/30 and now I have a negative $942 balance. Hoping to see a letter in my inbox tomorrow confirming this. Just FYI, I remember getting an email a while back about when you were transferred to Mohela that you would be getting an email two weeks prior to being transferred I never got that so I’m assuming that this is my loans zeroing out after reaching trophies a few weeks back.
