Why can't I trade anything in this stupid market? It's the one, single market that's completely dead to me and as far as I can see, I'm not being embargoed by Mali. Is it because it's a province deep inland and surrounded by a bit of Terra Incognita I can't even touch with exploration? That'd be seriously fucking stupid since it effectively makes West African colonies entirely useless as you can't import anything.
Where the hell can you even check your trade range for that matter (not the value, but where you can actually reach from one market to another)
