Servers are wiped every month, wiping all the ethanol and seed stockpiles. Once the wipes stop and the game goes live, ethanol raiding will absolutely destroy this game. There will be one group on every server that has a retarded amount of crops raiding everything in sight indefinitely.
Remove seeds from crop farming. Crops should be one time harvest. The farmer should then have to go OUT to find more seeds. The compounding effect of 1:2 seeds per cropout is just bad.
