I have a perhaps complicated question.
I would like to generate a new state, which I was able to do by adding entries in several files.
However, the visual assets on the map (cities especially) seem to be linked to the state for some reason. For instance splitting a state into two (one new state entry) caused the existing city to remain small (no growth), however relocating it to the new confines of the original/vanilla (no split) state did ensure it was visually growing.
Considering this effect, I started to look into how we can add new map objects, such as cities, farms, wood, mine etc. However I haven't been able to do so successfully. I looked into all the files, and eventhough I tried adding an entry in the "Victoria 3\game\gfx\map\map_object_data" files belonging to these assets respectively, it doesn't seem to add anything on the map.
So, in short: how can we add new cities/farms/mines/wood/ports and link these to their respective state?
