East Wind Campaign Ending and Achievements

[Winter]

Spoilers ahead, obviously.

So, last night, I unlocked the final mission Paradise Found, and chose to help James. After delivering the truck to Miller, and watching the credits roll, I was given the Game Over mission where I had to escape on my own. I drove my car into a rock at a very slow speed, the car stopped dead in its tracks, no damage to the vehicle or injuries on Kerry, and after a few seconds, my screen just went bloody and I died with the words THE END appearing on my screen. Since the game wouldn't let me reload a save for Game Over, I had experienced the single most anticlimactic end to a story in my gaming career. Game Over appears as the final mission in the Campaigns screen, yet clicking on it takes me to the mission Air Superiority for some reason.

Earlier today, I decided to replay Paradise Found and side with NATO. After delivering the final blow to the AAF, the credits rolled again. This time, I pressed Space to skip them as I had already seen everything recently. No achievement, no extra mission at the end.

I've unlocked 4 achievements from the East Wind Campaign - 3 for completing the Survive, Adapt and Win episodes, and one for the B ending.
5 hidden achievements remain. I'm certain at least 4 of those are locked behind other campaigns. But shouldn't there be another achievement in store for me after helping NATO? Did I ♥♥♥♥ up by skipping the credits?

Please clear this up for me.

the hidden achievements are for other campaigns except for one. When you select paradise found, click 'Revert' instead of 'Replay'
edit: paradise found not paradise lost lol

then when you complete it, you can skip the credits and you'll get transitioned to the final mission
