Polar Expedition achievement won't unlock.

[CrimzinD]

I've run through the thing like 40 times now, tried using someone else's save, finished the last level on the second world, and it refuses to give me the achievement...

[edited out]

No clue what's going on. Some help would be appreciated.

Was able to get my other achievements for other games, but SpaceChem's still won't work.

I can't get it either, and I passed Sernimir IV several planets ago.

Tried fast-forwarding through every level on the first two planets, and it still won't unlock.

You have to fast-forward the solution on the level BEFORE the south pole one. That's how it unlocks. (And also why it says "Reach the South Pole[...]".)

[CrimzinD]

I have completed both world 1 and 2, and fast forwarded through all of them sequentially. It refused to give it to me when it should, (upon completing 2-5, "There's something in the Fishcake".)

It doesn't give it to me when I complete "Sleepless in Sernimir IV" either.

I have the Achievements to geth the TF2 items, so I don't know what the hell's wrong.

@CrimzinD: When you look at the second planet, is there snow on the bottom third of it?

[CrimzinD]

I'm not sure. I just went to verify the files before I saw your post, and 1 failed. It's redownloading. Let me try now, and check.

EDIT: Verifying the game files fixed the issue. Something I should have tried soon after the issue occurred. The second planet does seem to have more snow than I remember, too :P

Thanks for the time. Hopefully this will help the other guy with the problem.
