Fix here.
I shrank the cloud graphics from a 112x32 image to a 64x32 image, which means there’s more repetition, but that can’t really be helped.
This is what it looks like by default (the background layers are disabled)…
…and this is my bastardized recreation. It’s uneven so that the tiles tessellate properly. If your map has holes in the middle, then some black squares may be visible; I can redo the sprites to cover them if that’s the case, but didn’t want to have too many sprites right off the bat (there’s a max of 128 at a time, and this layout has 23).
Here’s the clouds with all the layers enabled.
