I designed a house all by yourself but suddenly is no longer continued to build. what now?
save building as a template. Remove the existing building. place down the template and instabuild command it.
Make sure to frequently save.
Do you have enough materials? all doors, windows etc. ?
Do you have hearthlings as workers or did you promote everyone?
to use the console for instantbuild CTRL+C to open Console then type ib in the console with the building selected ingame and press Enter
