On the new anniversary edition gameboard (which is glorious) I seem to have noticed a point of conjecture regarding the border between sea zone 17 and the land territory Morocco/Algeria.  In my first game my British opponent (who wasn’t nearly as familiar with A&A revised as myself)  used his transport and land units from south Africa and invaded Morocco via sea zone 17 which the axis had left unoccupied by sea units (or land units in Morocco).  I immediately questioned this move since it is clearly illegal in the A&A revised edition but after careful inspection it appeared that the territory boundary lines allowed for this move and the Morocco territory does share a coastline with sea zone 17.  Is this an official map modification?
