Didn't get the 'Vanilla Crazy Cake' achievement

I just completed the last advance chamber without getting the achievement for it
How do I fix it?

Sometimes achievements are just not gained. Make sure you're connected to Steam while you play the game and have sv_cheats set to 0. Try the maps again and it should work.

If the achievement shows as unlocked on the in-game menu, then to get it to show on Steam use this fix:

Thank you Calmy. The trick also works with (quick) saved games. I tested it with advanced chamber four.
