Yesterday I made it to level 61 at the Arid Nexus - Badlands. Since then my XP indicator bar has stopped working. When I levelled up the bar stayed empty with no light blue progression indicator. Since then I have done several side missions including Monster Mash part 3, Breaking and Entering, half of Hungry like a Skag and a Snowman run. Also when completing the side missions the gained xp did not register on the bar at the foot of the screen.
This is a disaster when I am so close to getting through UVHM.
Is this a game bug? If so can it be fixed, if not does anyone have contact details for Gearbox Technical support?
