This is really bugging me. The article claims the fungus is an edible mushroom, but Pestalotiopsis (the spores on the right) is an endophytic, microscopic ascomycete. Not a mushroom and certainly not edible. So why is there a picture of Pluteus on the left? I can only imagine the author googled “Pestalotiopsis mushroom” and grabbed the first picture that came up.

There is a node for Y-sorting in Godot 3, is that what you’re thinking of? Y-sorting was rewritten for 4.0, so that node doesn’t exist in the latest version.

Your Godot problem sounds like you might have ordered your scene tree wrong. The scene tree reads from top to bottom, so if your interface elements are further up the list than the map, they draw first and then get covered up.
