Usually, the annuals come away the other way around. ProFantasy spots an artist already doing an interesting style (maybe as a result of a tip from the community), and then works with that artist to bring their style into CC3+ (as an annual or symbol set, assuming the artist is willing obviously). This basically means that the map types will reflect what the artist is already doing.

Very few styles have matching overland/city/dungeon styles. The only ones that comes to mine is Jon Roberts (divided over several annuals with all of overland, city and dungeon) and Mike Schley, with the main set in CC3+ itself, and SS4/SS5 dedicated to dungeon and city. But it isn't the common approach. I guess partly because artists have their preferred environment, dungeon scale artist doesn't necessarily make city or overland map, and a lot of the styles from CC3+ is the artist adapting their existing style for CC3+.

That said, since a city, dungeon and overland style isn't linked together, there is nothing wrong for Sue to make an overland style for 2021, and a dungeon style for another year, like 2022. Both issues of spectrum had to go in the same year because just half of it would be a bit weird for the purchaser of only one of the annuals, but a city style is still fully usable even if you don't own the annual with the overland style. If there are any repeating files (like maybe some of the fills), they can easily go in both.

As for Sue's comment that it has to be a city style in between, I disagree. These are separate map types, and there are no reason all three have to be made. Nice, yes, but not required. Just look at the Mike Schley style. Overland was released with CC3+, SS4 Dungeons of Schley was released almost at the same time, while SS5 Cities of Schley was only released many years later.

It may be a hidden file, make sure you show those. If that file is missing, there are no cache, which should make the thumbs show up fine, although it takes a bit longer to open the dialog

Hmm.. That size and filecount basically matches the installation directory of CC3+ (as opposed to the data directory). But you don't get asked about the installation directory during install, the installer only asks for the data directory, the installation directory is ALLWAYS placed on c:\Program Files x86\ProFantasy\CC3Plus (Notice the Program Files (x86) in there instead of ProgramData, they are easy to mistake for each other).

Did you ever manually move the installation directory to this location during a previous install? (It is possible to do, allthough it is really unnecessary, because as you just saw yourself, it is only 23 megs, so it doesn't really take up any space, even if you have the tiniest SSD in the world for your Windows install moving the install directory doesn't have any impact).

Are you sure you picked d:\ProFantasy for your data directory when you reinstalled CC3+ this time? Or even if you picked it, maybe you got a dialog telling it was already files here so it couldn't use it and you just ignored it and clicked proceed? (Which would have caused it to revert back to the default dir).

In any case, the data files should not be installed to the same directory as the installation files.

At this point, since you were reinstalling, I am not sure if d:\ProFantasy is part of your install at all. You can check this by right clicking on the CC3+ icon on the desktop and choose properties, and see where it is launched from.

The edit feature can't handle changes like that. Once you put a break in the wall, it is no longer a polygon, but a line. It might even be more than one line if you have multiple gaps. You can delete the walls, then use change like draw tool on it to bring it back to the original state, then you should be able to edit it, but of course, the gaps will be lost and have to be recreated later. Otherwise you'll have to do with the normal node editing tools.
