Yesterday 7th medium base assault mission.
Cannot complete it as I have no medium bases, all hard 3 diagonal lines are full.
Try to respawn a base but not going to get it there in time.
Why?
It isn’t an issue of the game, if you have all base-slots full with lvl3 bases. Destroy some and fight on, new bases should spawn quickly.
Remember not to leave a base/mission area once you started the assaults, as the scores for killed machines may result in an upgrade to a lvl3 base quickly.
Don’t die, don’t fast travel, don’t retreat.
