So I've been trying Vintage Story on Manjaro for the first time and I'm trying to reinstall 1.20.12.

Thoughts on what I might be doing wrong or missing in the copy/pasting, here?

I've pretty much gotten everything but the last step which is adding a layer of dirt above the trap. Right-clicking on the dirt crumbles the whole thing apart, right-clicking while holding shift does the same. Left-clicking does nothing. What am I doing wrong?
