To upgrade the D.A.V.E to lvl 6 i need 28million putty but i have all 5 storage silo's ( max amount) and maxxed lvl 10 and each recorse space i can store 21mill how do i get more space in the silos?
You can't get more space in the silos since you max out the number of silos. All you need to do is to level up more, so you can store more money and items! Good luck!
