Hi guys! I've finished the game but I missed the "Montana Mystery" achievement. Are there any special steps for this one or it simply didn't unlock during normal play? Thanks!

only problem i encountered was in Malibu Beach trying to attach the sail on the sailboat. It wouldn't let me and so i cant continue. I'm stuck and is the first time i ever had a problem with these games. Im using Win 11. Please fix it before i list this on my review!...
