I think it works as stated

Off map communications are not disastrous they just become worse you can live with them.

Morale is another matter it makes things very hard especially because more often than not it happens around or just after the hit for 50%.

As this is MBT start a battle hit your HQ with a large CM barrage to destroy it then wait a couple of turns before engaging the enemy preferably with the odd unit out on their own like a scout or ATGM team.
Save & play both games from there.

Better still your opponent should be the same country as you.
