29 and 37 should probably be connected, as should 20 and 25, unless you want those cave tunnels to be special. But then make it clear through the province borders that this is not just an oversight. There should be dotted province borders between 25/27/29, I think, and fixed starting locations, since the map is symmetrical. Probably #17 and #38 or one of the provinces bordering them. The dotted province borders makes it look like 33 and 37 should be connected, and 17 and 20 don't.
