Vanilla Crazy Cake bug problem

[Alpswat]

I had the 6 maps completed. But the sixth map i completed it in Steam offline mode, and I don't have the achievement, What do you think? Reinstall the game and complete the six maps again or try to complete again the sixth map?

The next time you play Portal in Online mode, click on "Achievements" on the game's main menu screen. Does Vanilla Crazy Cake still show as locked, with progress 5/6?

You should just need to "complete" the sixth map again. If you have a saved game part-way through the level, start from there.

No, sorry for the amount of time to answer it, but i didn't see the answer before, sorry!
No, it appear to me 0/6

I had the same problem: you can't just complete it again to earn it. I don't know how to fix it short of resetting all game data

First make sure that Bonus Maps shows you have completed the required maps.
Then use the fix:
