War timeline: https://politicsandwar.com/nation/war/timeline/war=1553348
Issue: I started with a total of 12 MAPs and performed two ground attacks both with 'Do Not Equip Soldiers With Munitions' selected, both were 'immense triumph's. I'd expect this to cost 6 MAPs, but the total military action points available to me shows as 9.
You can see in the 'Calculated Defender MAPs' column in the war timeline my MAP count drop to 6, before being bumped back up to 9.
