Everyone Loses ULX rank?

So I got on my server today and notice that ALL of my staff and VIP’s have lost their ranks? I checked our data/ulib/users.txt and it’s EMPTY? The server was just fine yesterday. Anyone have any ideas?

Edit: My staff is saying that there was a map change (I use GLMVS) and everyone lost their rank afterwards. I recently did another map change and now all of our groups are gone? (Except default ULX groups)

In the future, make sure you make a backup.

I did have a backup but it’s quite old. I’m just having NFO do a backup anyways.
