I got a Warning in my simu.log:
Warning: fabrikbauer_t::increase_industry_density(): No suitable city industry found => pak missing something?
What means that and how can i fix this?
As far as I know it's because Simutrans was trying to create a new industry but failed because none matched.
Basically, the pakset lacks a city industry for the available climates in the map and current timeline. So the chain could not complete.
