Let me check and see what I have for saves and if I can find one for this part. Nope, sorry I don't have a save for that part.
In the meantime, I did find this on the Steam forums: "My game crashes when Chipeto gets stuck on the rock. I tried to play with The Squig's save file, but it still crashes. Can anybody share a savefile starting right after that moment with Chipeto ?
EDIT : Actually it works now after I deactivated vsync. That's weird."
And someone else had luck getting past this point when they opened the game in XP compatibility mode. I was going to post a link to this thread, but I see Marian has beat me to it!
Heading out to the gardens...
