I already made a functional tilemap for my top-down RPG, I made some mountains to test some combinations.

Here’s also the Rules file:

And now Im trying to make a new layer so I can make bigger mountains with multiple floors. I tried duplicating both the Rules and Map file layers (as shown on both images)

But when I press Ctrl + M on the new “mountainbase2” layer, it creates a weird output layer, so im not sure if it’s working or not (since it does shows some tiles, but only a few, like in this image):

Is there something Im missing? or is there a simplier way to make more mountain floors on top of each other?
