Re: Pesky Land Bridge connecting gondor and harad
Land bridges are represented as green lines in the map_features file. Simply delete the line (hope yo know the approximate location) by over-painting with black (RGB value 0,0,0) - back up is advised.
Once you have removed the landbridge and saved map_features you need to delete map.rwm for the change to take effect in the next game. Please note that doing this and starting a saved game might have some weird graphic graphics effects on the strat map
