Did they combine together with the other two rock star scavenger items and complete the scavenger hunt? You have the rockstar so seems that may be what happened.
ohmygosh is it wrong to ask questions in forums now? People are sad. That's what forums are for, ppl! You were all noobs once too and probably had a similar question at one point so
Why be a dick? you people didn't know that shit when you first completed a hunt either. Swear some of you mother fuckers should go talk to ppl the same way in rl as you do on here then post how many ass kickings you recieved.
