No more missions will appear
I'm at Level 20, with golds at every map that I have available (I have the ANBAs up to Firefly Landing and the rest all the way up to Bouncy Hills). The only Tier II bike I have is the Jackal. Aside from more ANBA challenges and a mission to get a Tier III spring (which I can't get without a better bike), there are no more missions available to me and there haven't been for quite some time. What can I do?
(I would have posted this in Bugs/Glitches but I can't tell if this is a bug or if I just ****ed up somewhere)
