A base is fighting to it's front and to it's flank .
The UG it fights to it's front finds itself engaged by antoher UG .
May the player who was engage dto the front and the flank choose a MF2 to turn it's base towards the UG that is on it's flank as the formal contact is now otherwise engaged . The only info is that MF2 enables you to turn and fight an enemy that you fight on the flank with no restrictions if you already fight to the front ..
In my case it was simple calculation as if I turned my base, the new flaking UG would fight on white dice but the flanjing one being now deprived of it's +2 flanking would fight only on green vs green and not yellow vs nothing
Seems reasonable to me. The restriction is you must turn towards a bases that is in frontal contact with your flank or rear.
