Unmap a room

How do I do that?

I looked it up in the Internet but my Code does not work :smiley:
I want a specific room not to be shown on the map after compiling.

Every turn: unmap Sammlung;

Which map? The one in the index?

You have to define the room without a relation to another room to start and then add the relation later.

After some thing happened:
now the kitchen is west of the living room.
