A Ford is when two docks are next too each other. Used to represent river fords on maps.
In Beta 3, You could take your movement on land, move to the first dock, move to the second dock. Then, the next turn, you'd have you're full movement as a land creature to move away on land.
In Beta 4, you finish your turn on the second dock, but the next turn, you are still a boat and have only 2 movement on land.
If you can change this back to work as before, great. If you can't change this back -- or don't want to because of some other gain with docks, tell us, and us make makers will change the fords back to bridges.
Still, it was nice to have fords -- slowed you down for one turn, but just one turn.
