This is the puzzle I mean, the one near the beginning after you move a bunch of rocks out the way.
-When I attach her to the beetle and have it push her off the edge then carry her back left, she gets caught on this bit of the terrain.
-When I attach her to a rock, then have the beetle push her off the edge and then push the rock left, she can go further under that section and I am able to retrieve her from the other side to progress.
