Those maps unfortunately uses the old version of the CSUAC (the current one at the time obviously).

At one point, the CSUAC had to be rebuilt for CC3+, and at that point the folder structure was also changed. Vintyri only maintains the newest version, so the old version is no longer available. The new version do contain all the symbols, but the paths are not the same.

There's no way to install it that will make this work, you'll have to manually replace the symbols with their counterpart from the new version.

This is an effect of how the template is set up, the lower left corner of the map border is not on the snap grid.

I have no idea why the template was set up that way, but it looks a bit weird.

Anyhow, to work around this, don't place the grid during the new map process. Instead use Draw -> Hex or Square overlay after starting the map, and instead of clicking OK in the dialog, click select points instead. This lets you put the grid points instead of the grid using the map border as reference, and if you have snap on when doing this, it will align perfectly with the snap grid.

(You can also use the set snap grid option in the dialog which will then fix the snap grid, but the existing snap grid is lined up with the background, so it is better to use it.)

This is due to how symbols in CC3+ work.

When you place a new symbol in your map, the symbol definition for that symbol is stored in the map, and every copy you place of the symbol reference that definition. However, the identifier for each definition is the name of the symbols. So, what is happening here is that you already have a definition in your map for Pine Trees 1, which you got when inserting the SS1 trees. Now, when placing the same named symbol from another style, CC3+ just sees that this definition already exists in the map, and uses that one (There can't be two definitions with the same name, so if it had copied it anew, it would have overwritten the old one, replacing all existing symbols in the map instead)

To work around this, you can rename the SS1 definition in the Symbol manager (Symbols menu), or just delete it outright if you don't have any trees from the SS1 style placed. Deleting a definition with symbols existing in the map will delete all references from the map.

Hit Tab (while moving something). That changes how cursor previews are rendered.

This is due to a corrupted entity in the drawing. There is an ellipse with a negative area there. Just delete it and the drawing should be fine.

To delete it, use :CC2ERASE:

When asked for a selection, then type in #104753 on the command line and hit enter. The command line should say that 1 entity is selected. Do it.

The #-character here is to tell CC3+ that you want to select by entity tag number, and the number itself is the tag of the corrupted entity, as shown by list.

To find this misbehaving entity, I went through the sheets 1 by 1 to see when the zoom failed. That would be the sheet the entity was on, walls hubs in this case. Then, I just started deleting entities from that sheet until the zoom stopped failing. In this case, it still failed even after deleting all the entities on the sheet, so I did a List on (A)ll, and that revealed the entitiy.

Note that to recover from a corrupted zoom like this, as long as you have any text in your map, right clicking any of the zoom buttons, and picking To All Text, and then picking one of the text entries in the box will get you back to a normal zoom level where the zoom out/in buttons work again. In the case of a corrupted entity like here, the zoom extents button won't be working untill the entity is found and dealt with though.
