Man, you're on a rampage today....

Deleting them from the map still shouldn't affect the symbol catalog though. After opening the problematic map, did you try and change symbol catalogs to something else, and then back to the vegetation catalog, using the symbol catalog button in the top toolbars?

As for copying thing to a new map, that is easy. You can either copy everything to the clipboard (Edit -> Copy) [Just keep an eye on the prompt to make sure you complete the command properly] and then paste it into another map, or you can use Draw --> Insert File to insert the old map into a new one.

Whatever you do in Symbol Manager in your map only affects what you see in the symbol catalog window when you use :ICON_DRAWING:. No matter how much you mess around, you should be getting the normal view when opening a symbol catalog, for example by clicking a symbol catalog button.

(Only way to mess with the actual symbol catalogs is to open them up for editing using file -> open as opposed to loading them into the symbol catalog window)

This set of maps have now been added to the atlas. Thanks for the great contribution.

Everyone have the CC3, DD3 and CD3 buttons, as both dungeon and city tools are included in the CC3+ base these days (Only the tools, you need the products to have the artwork, but the tools are very useful with artwork from other products, like SS4/5 or the annuals)

The WW2 button should be added as long as you have the WWII.mnu file in your data directory (which should be put there by the installer).
