Endless Setlist 2 Problem

[TheGearbox]

So I spent the better half of my day, completed the endless setlist, got an achievement, checked if all the songs were there and I had 84. Boot it up today and everything was gone. it now just tells me that I can do the endless set list, and I lost the songs I unlocked. Frankly I'm strait up pissed, and would like some help here.

This could be a profile issue.

1. Were you playing on one instrument during your entire play session, or did you change instruments?
2. Which achievement(s) did you unlock?

did ou have a modifier on? that's always the problem for me.

he says that he got an achievement so modifier is likely no. it could be a save issue
