Bad glitches that need fixing

So I haven’t played Borderlands 2 in about two months, and I just hopped on to my overpower level 8 gunzerker, and my overpowered levels were no longer there. I had all my gear, but it acted as if I didn’t do the overpower levels. If someone could help me fix that, it would be great.

You may want to contact the Gearbox BL2 tech support rather than posting in this particular section…
