Glad you managed to sort this out Scott. I found the download speed was VERY variable yesterday evening when I picked-up the latest CC3+ Update (about 4 hours before your own attempt, from the time-stamp on your first post). Initially Windows "estimated" 20 minutes, which then rapidly increased to over an hour, before dropping back sharply after a few minutes. It actually downloaded in under ten minutes in the end. Seems likely there were some oddities ongoing all over, however.

This afternoon here, I had my connection drop-out entirely for no obvious reason at all about 90 minutes ago. It does this from time to time, which I assume is something fairly local, though actually, it hadn't done it since last November till today.

Yeah; appreciate the problems!

Good luck with it all anyway.

Who? Me? Ow! 😁

It's an interesting idea Jim.

Not sure the current walls work for a cavern though - they're too regular. Might be better using Sue's cliffs for those too, though that might mean masking the top of the cliff symbols to make them look more like walls and less like cliffs.

Possibly a fractal polygon running out to the map's edges would be better to show it's a huge cave instead of using the cliff symbols though. If so, that would probably be better created using the Color Key Effect, drawing a suitable fractal poly for the cavern's interior, then covering the entire map with a "rock" bitmap fill texture rectangle on the same Sheet, and turning the interior fractal poly to a solid fill, colour 6 pink to create the cave. Oh, and moving the "cutout" fractal poly above the solid rectangle on that Sheet, of course! (Voice of experience...)

Does this mean the "dungeon" rooms and passages are then walls on the huge cave's floor, roofed over so from inside you can't tell you're in a gigantic cavern?

Indeed, much improved.

Maybe increase the glow on the numbers to make them more legible.

The Tower top looks very flat though. The outer walls need some sort of shadow to show the floor is below them. If it's the exterior top, that may complicate matters, as you'll need different length shadows for the higher and lower stretches of the wall tops.

Further on the latter point, and if they are, the crenellations need a little adjustment too, as there are what seem to be large open gaps at the northeast and southwest corners currently, which is not realistic.
