As we say in game development world, coding isn't the longer part.
I passed 2 days to finalize the new infrastructure (inflatable greenhouse) and rearrange some of the products and infrastructures data.
So now it's time to implement the rest of building construction rules: assembling, building, staff management, and finally transition and production delay.
I'll also implement a panel for infrastructure configuration/assembling-building.
Ranting finished, it's time to dev ! :)
