Rain for days after a long drought period is actually really bad because the ground is too dry to take up all the water, so everything gets flooded instead. Guess the physics in this world work differently, huh ¯\_(ツ)_/¯
@shiirosagi You're right. This type of oversight is too common, and makes for poor world building. Not diversifying the crops forces complete dependence on imports and is a single source of failure. History has plenty examples of how this can go horribly wrong (e.g. the Irish potato blight).
MC has perfect control of the weather, in universe it seems pretty easy to handwave away negative effects from not diversifying crops, sudden rain after drought, etc. he literally has a biosphere fellas
In the french roleplaying community we have a say for people who contradict the DM too much : "TGCM" (Ta Gueule C'est Magique) which would translate to "Shut up, it's magic".
I think it applies well here ^^
i see no issues with planting an entire territory weith a plant "too rare to be bought" definitely wont crash the market or anything, also no explanation for why there wasnt catastrophic mudslides and damage after the rain following the years long drought
