Thanks @Wyvern. They are now in the atlas.

Maps are now in the atlas. Thanks for the contribution.

Sounds like you have started your map from the CC3 dungeon template instead of DD3 dungeon. CC3 dungeon is a cut-back style intended for people who owns CC3+, but not DD3 to be able to create basic dungeons. This template does indeed not contain the Flagstone G fill. It is possible to add it, but you are probably better off just starting a new map in the DD3 Dungeon style.

Yea, big cities can get pretty time consuming. I tend to be too lazy to do them myself. Seems like you are getting there though, slow and steady is often the key.

Maps processed. Thanks @Ricko
