Has happened twice

Yes, especially with the rules text gone. I've played a lot of Cartographers and still confused it. Maybe have option to use old view that shows rules. The previous view also worked better on my phone - now I have to keep scrolling up and down. Thank you.

Actually, I think Treetower, Sentinel Wood and Stoneside Forest look alike and mix those up. Treetower and Sentinel Wood look almost identical, and on top of that, all the forest cards show connected mountain spaces which makes me think all three of these are Stoneside Forest.

I don't remember experiencing this problem with the city cards, just the forest ones.

I agree with Livini; the tree cards are easy to mix up, especially Treetower and Sentinel Woods. Great City and Shieldgate also have the same issue to a lesser extent. It would be helpful to either include the rules directly on the cards or redesign them slightly to make it clearer which is which. Changing one card from each pair should be sufficient.

For Sentinel Woods, a slight repaint could be very effective. Using a more eye-catching color for the side of the map would make it clear that the edge is the key feature to focus on.

As for Shieldgate, I suggest replacing the large 5-block in the center with a smaller 4- or 3-block. This would keep most of the card's design intact but would make it distinct enough.
