I reported this many moons ago (CoI?) but am still occasionally seeing it. Pic below is a composite of the starting and ending German map control on Oss before and after a multiplayer meeting engagement. None of the German teams moved during the 15 min battle yet the Germans were given a VL and additional deployment tiles (boxed in red).
None of the UK teams moved either but the Allied post-battle map control was the same as its pre-battle control.
