This is new behavior in B4.  Previously if my army was trying to move past a friendly of SK army on the strategic map , it would mov up to it and stop. If i clicked the desired location again it would continue either in a straight line (if it could) or go around the offending tile.  Now in B4, i must move my army one tile at a time to pass the offending unit.  Sometimes ( say if my army is starting several tiles from the "blocking" unit) my army will not even start to move; i.e. clicking the destination tile does nothing.  I must move my army up to the blocking unit, move single tiles around it, then proceed. 

Note: When i say blocking unit, it mat be directly in my path OR only adjacent to it.
