if you are lvl 30 and doing lvl 32 hearts i dont see problem…. It is normal when you complete map you are under max lvl of zone. I did lvl 40-50 started at lvl 42 and ended with lvl 48…. still i dont see game fighting with me because there is another zone of lvl 45-55 so you can go to other zone. If you are lvl 30 and finish at lvl 31 you still have 2 zones to complete with lvl 31
