What are the possible reasons for the empty tiles in my city centre?
The suburbs are fully filled with houses, but OpenTTD doesn't seem to bother to use the empty land in the city centre to build more buildings. Why?
I have waited forabout 80 years (in-game time), but the empty tiles are still unused.
If I reclaim more land by raising the water tiles, new buildings will be built, but OpenTTD will leave some tiles unbuilt on the new land.
