User blog:Blyndblitz/Sharpshooter glitch

So I completed the mission Boar-B-cue on my low level profile, but I still haven't unlocked the sharpshooter. I'm level 16 and my missions are to attack tronk (the battles are level 25 battles so I can't complete it), to build the concrete plant which should be unlocked at level 19 but it is impossible to build due too warehouse stuff. My other mission is to train rangers but I'm not level 20 yet. Please help
