There are sets of boulders on the hills surrounding the gated village that is pillaged in chap (4?). They have no collision and can be walked through.

I was trying to see if I could jump over the gate somehow, and I noticed some invisible walls preventing that. But, near the bottom of the invisible barriers, the rocks are not solid.

I wish that I could give you better sets of coordinates. Is there a command that I can run that will give me coordinates of bugs like this, so that you don't have to search for what I find?

The most noticeable ones are near an alien artifact next to a cactus.

Thanks!
