Current questions and answers regarding the map editor.

I managed to place buildings from a town onto the adventure map; I even extracted the market from a Necropolis town. The small problem is that if you place it at coordinates 1;1, for example, it will end up floating somewhere above the other end of the map and at a height of about 40 cells, which makes sense since the market in the castle is located on a high tower. But you can adjust the coordinates and place it where it needs to be. Of course, it's not a fully functional building, but rather it has the properties of an effect, but you can place it over some object (like the eyes of the mages, for example) and write the necessary trigger.
Adding a new type of town is a very interesting idea; if you have any ideas on how to do this, please share them.
