Telegrad Beach Cavern
There's a water pool just to the right of the path leading to the hole down to the crystal pile, and the corner of this pool has a water tile that's unconnected to the larger body of water, with harsh edges. Should probably be a sand tile under that curve, instead.


Duyuei Outskirts
The leftmost farm just before the warp towards the area with the Sea of Clouds has a set of trees just to the right of it where the top edge of one part of the tree line doesn't connect to the other edge, leading to a harsh gap. It's probably missing a tile to connect the two together.



Same map - the ruins mistakenly doesn't use any top edges. Only bottom and middle edges for the wall, The angled pieces, do however use top edges, leading to an awkward combination. The shading tiles are also incomplete, and don't actually act as shading because they're only on the angled bits, unlike other ruins.


Meiaquar Outskirts
Same issue of incomplete shading. The damage on the top layer is cut off by the window, as well, which is just pure accident. Shading should continue up the the sides.


Geladyne
The top right corner of these wagons doesn't have a tile beneath it - you can see the void peeking through where the other two edge tiles of the wagon don't have this problem.


Terra Flama
This is in the room with the Cypelle that you have to hop around to obtain. This sheer cliff seemingly is missing a jump point down, so going the long way to get here leads you to a complete dead end, you have to go right back. The cliff also doesn't connect to the wall at it's side, leading to a jarring end at the bottom.


Here it seems like the cliff is trying to join to the wall oddly, you can see small corner bits on the tiles just back from the wall, as well as the other corner bits joining into the lava.

Checked over most of these (didn't stop by Telegrad so don't know if those got done) and most were indeed fixed. However the ruins in Duyuei is now missing the top corners instead, and the shading is still incomplete on the top layer.



The trees are also still connecting really wonky here.

Edit: Beach Cavern's fine.

Although the thread didn't get a mention of being fixed, stuff was fixed in here. Now the ruins no longer have the wonky side connections, but the shading still doesn't go round the side on the top section of the ruins.

The same shading issue appears on the tall tower in Meiaquar Outskirts, too! Both bottom and top, iirc.

Nothing appears to have changed regarding the treeline connection. Still looks how it does in the screenshot.
