I not agree
So originally it was a ONI safe house/research lab/storage facility on the mountain they landed on.
Only green and Daniel were supposed to be there then somone put Z19 in there which I assumed that z19 was on a different ship
Then the avalanche blocked the entrance which eas magically fixed
And then Survivor messes it up worse by making it a bunker in the valley itself instead of the mountain WHICH IT WAS ORIGINALLY.
Oh gött ze plot holes
This is ticking me off
