Ok I have done EVERYTHING there is to do, but get LASt map piece for the new hidden area. I am literally down to 40/40 in the Crossbow Hunt Series to get the LAST map piece, but it says I need to upgrade to a crossbow with 951 power. But I only have 16 coins. Need like 50 more to upgrade to that power. But I have completed EVERYTHING else there is to complete to earn coins. So how the hell am I suppose to upgrade to finish and get the last map piece?
