PLEASE PLEASE PLEASE, don't put landblocks in 0.8! PLEASE!!!!!! Landblocks ruin gameplay by stopping factions from going to war with each other. If you don't want people to go across the Sahara as it would have been hard let them do so, but make it difficult to do so. Make sure that all generals that are in the Sahara get a trait which restricts movement and that goes when they leave it. Brilliant solution!
