Ok so the second and third star rank promotions are working now so that's great.
The thing is that there are supposed to be 2 unique items in the Hunter's arsenal but there's only one right now which are the rough rider boots for two stars.
Also I'm not sure exactly what are the perks for getting the promotions because you still can't do elite bounties and there doesn't seem to be any changes to other parts of Shine Town.
Don't know if this is a problem on my end since I'm playing on mobile, but I've never used any cheats for this game so that shouldn't be the cause
