Weird I never had any issues with that mission and I finished survive campaing more than once.

I've played this mission multiple times but Miller never died on any of these playthroughs

Fixed in 1.32 version

works perfectly now

Looks like its fixed now

If you drive with your vehicle to a camp with weapons,ammo,mines,launchers that you put in its cargo they will be saved in ammo crates (tested 4 times in Adapt Campaign). But unfortunetly vehicles are not saved in hideouts/bases.

Also in second Adapt "Wspólny Wróg" mission when you help Miller he says to Kerry "So you meet with the rest of his team" its not translated too
EDIT
At the Campaign selection menu WIN needs info needs to be translated also the quote cutscenes before mission needs it.

Have you tried to equip and unequip your explosives?

happends mostly in Kavala and other towns surounding it

Status?

just enable arma 3 in firewall
