Hi there 👋 I'm not sure how I can help. I tried to arrange the tiles intuitively on the sheet. You can try joining the Mana Seed Discord server and sharing screenshots of problems you're having. Then I, or other Mana Seed users, can maybe point out where you went wrong or which tile you should be using in a given scenario.

I tried joining the Discord, but it keeps saying “Unable to accept invite,” so I’m not sure why. At this point, I mainly want to understand the 16 border tiles used for the cliffs. I’ve managed to figure out the grass and some of the other autotiles, but I’m still struggling with the cliff borders and how those 16 tiles should be arranged to make the cliffs work properly with the autotile system. I’d really appreciate any guidance on this.
I honestly don't know how to help you. I provided many example images, and even a sample map TMX. The tiles are laid out on the sheet in an intuitive way to help you understand how they fit together. The cliff edges should be pretty easy to identify, put them at the top of the cliff faces. Make sure the horizontal striation lines match on the cliff face. There's not much more to it.
