Help for 100% devil's razor

I have finished everything that has been suggested so far. even the claptrap dancing mission the only thing missing for me is the repeatable quest at the billboard its not showing up for me. I have finished TVHM campaign and other side quests also. Is this a bug?

I think that quest requires you to complete a quest on Eden 6 first. Something to do with a sign spinner guy?

ok i will look for this ty

It’s the burger quest. Should be a sign spinner in the rebel town in Floodmoor Basin, then one at Roland’s Rest in Devil’s Razor. I forget if there are others in the sequence, but I think you have to have started with the Dynasty Diner quest in Meridian Metroplex on Promethea.
