Thanks DDW – ok, if I stumble I will post here. I guess the issues are “game related” as they’re about the installation and playing of the campaign anyway.

Your problem – I’m going to answer it EVEN THOUGH I am unfamiliar with the mechanics of the game (queue derogatory remarks)…..

They’re named Land Bridges in the game and in the files relating to them so MY assumption is that they cannot be blocked with fleets as fleets are still, in-game, classed as sea units which can’t block or operate on land.

…however they can sail across these land bridges as they are just software mods designed to allow land unit transport. In other words they are incomplete Mods deliberately but as incomplete mods they do not allow for every variant in the game.

In this case the game may be looking at them as 1) Sea & 2) Traversable by Land forces but then it looks at the sea units and they can 1) move on sea so as this is the first rule it allows the ships to move across the land bridges BUT then it looks at item #2 and will not allow them to block land units as its hardwired that no sea unit can block a land unit “on land”.

Hope that explains my theory on it, wonder if I’m correct?

To be honest I don’t know the thinking behind these Land bridges, can someone tell me why they have been added? Is it just another unrealistic mechanism to encourage the AI to be more aggressive? or is there some historical accuracy or other realism behind their inclusion?
