OK, so after an hour of checking, downloading and reinstalling, I have the complete 2018 Annual installed (again...), and an identical problem to Julian's still. No varicolor bushes unless I load from the PNG files, as described already above.

Before I reinstalled, all four of the Japanese Temples FSC files had dates of 31/08/2018, and they all still do, so I can only assume they were never updated in the final (i.e. the one huge, ~2 GB, Annual download file for 2018).

Hopefully these can be easily redone to correct the problem, though I imagine everyone who owns that Annual except Sue (!) will then need to reinstall the updated version.

I can confirm the problem Quenten reported. At a guess, it may be to do with the CA187_MediumIslandChain.esc file (I'm not familiar with the file type, so don't know what to open it with to check). That's the file being accessed by the macro that runs the drawing tool, at least, and it seems to be the main difference between the three Island Chain drawing tools from a quick look.

You can just use one of the basic landmass drawing tools in the style to do this. Note you can also delete individual islands and replace them this way (as I just did a quick test doing precisely that).

Debris on the lower floors looks a little flat; as if it's part of the floor itself, not sitting on it.

Also, if the structure is stone, the fractured edges look odd. Generally, if damaged, you'd expect entire stones to drop out, or parts of individual stones, as well as leaving surface damage to those that survive. The very fiddly raggy edges that cut slightly into neighbouring stones and wander across others look very unnatural. Right now it looks very like the floors are made of thin sheets of acetone-melted expanded polystyrene.

That impression is also reinforced by the lack of stone debris on the floors below; it just seems to have vanished.

You might want to tweak the shadows on the upstanding parts of the battlements; it's strange to have the same length of shadows from them on the ground as on the roof, as if the roof's floor is actually level with the grassy surface, and the tower's interior is really below ground.

Certainly, I found drawing "Naughty Lass" quite a challenge overall. There's a particular complexity in trying to visualise things in 3D to be able to draw 2D versions from top-down and side-on viewpoints, and deciding exactly which line you'll pick for the cross-section, etc. There isn't an ideal solution, so you end up just picking whatever seems to work better, and hope users/viewers will be able to tell what was intended.

There is a similarity to the cross-sectional views of caves we've discussed before here, though with a ship, you can't usefully vary the line of any sections, as that just makes it still harder to draw for a vehicle.

I'm not saying it will definitely help, as I'm not sure what changes were made when the Ships Annual was updated, as they were drawn only using the original, but I had to handle similar deck-level elements, and other features, when designing "The Naughty Lass" for the Atlas. For ease, you can pick up the deck plans FCW here, and the sideview here, in case those may assist.

Note though that I did "cheat" with the yards, by having them piercing their respective masts, partly because it's a magical vessel, partly because I was trying to avoid needing to show the complexities of the rigging...
