It looks like Glopso reduced the cost of “Finding Rocks” by their own Intelligence, and set their Learn to blank - this isn’t quite a Scientific Convention (which should be processed for every Caveman), nor is it a Cave Painting (which requires something to paint with, and doesn’t blank a Caveman’s Learn). Glopso also turned a Stick into a Pointy Stick, without having knowledge of Making Pointy Sticks.

I think this is all extremely illegal, and I’ve reverted it, but I’ll mention it here in case I’ve misunderstood something, or if Glopso’s misunderstanding of the mechanics is more widespread.
