White Screen after loading (Mission Editor)

[JustRyan]

So i made a mission were i had 3 squads of Marines (2 assault and 1 support), had 2 helicopters (1 transport that was filled and 1 attack helicopter), 2 Abrams tanks, 1 LAV.
Mission was to assault a oil/fuel station that had 2 rifleman squads, 2 assault squads, and 1 support squad. Behind them was 1 attack chopper and 2 APCs.

When i loaded the mission up i was shown a white screen and couldn't do anything :(


Does anybody have a fix to this?
The only mod i am using is Island War 2017


EDIT: FIXED! I had to remove a squad
