Hello,
Situation
Playing skirmish mode just against AI (WITH SKULLS ACTIVE) on windows 10 PC
After the game starts I immediately begin to lag and drop to about 1-5 FPS and will freeze after about 15 seconds of game play. I then have to force close Halo Wars 2. Now its worth noting that I do not suffer this issue when there are no skulls active nor do i have this issue when Skulls are active in campaign. I have tried using different amount of skulls and different combinations on different maps with different player counts, but the result is always the same. If i have any number of Skulls active in skirmish the game lags to 1 fps and then crashes.
