Cradle of Zen (.map file) and a question!

There is one reason why that is no bottlenecked. And that is because most of it is Swamp, and there are very few units with any sort of Swamp Survival. Also the "PURE" bottleneck when moving into two different terrain type flags (Like the terrain switching from Forest to Swamp) caused the superslowdown of troop movement. I removed most of those including that one.

If you don't like it, that is of course your preference, but if I left all the swamp provinces exactly as they were and didn't change terrain the speedbump, 1 Strategic move a turn, would remain, as it is now the addition of different neighbors with a movable terrain type (Plains/Swamp) allow at least nations that are supposed to move well in that terrain (C'tis) the chance to do so, while still slowing down every other nation.
