girl randomly falls through ground near the corner on the way to platform that raised in order to get necklace [.006]

raise platform, go through window, past obstacles, back through window to get inside, turning the corner to go left to get the necklace girl falls through ground
doesn't always happen, I even tried to run over it multiple times and it didn't happen but I have had this happen in 3 separate gaming sessions
I was always running
I always run

walking controls are kind of clunky

I cant seem to be able to reproduce this bug, it would be nice if someone have a video of this.
