I've been doing river raids for the last week and it takes forever to progress and I can't tell if it's a glitch or the game, can someone help me out. It cost over 1000 supplies to upgrade my ship to max and the best ill get is 240 why? I now need to go on 3-4 raids just to upgrade the hall. Also the river raids are so boring going back after 2-3 raids since my inventory is full.
