I was having a problem with friezes on a house and tweeted SimGuruJohn. He asked for pictures so I'm posting it here.
This is the house showing the frieze problem.
I then demolished all but the balcony and rebuilt the upstairs with only exterior walls. The frieze worked fine. I then added the interior rooms including the L shaped upstairs landing. Seen here:
I then deleted the flooring over the living room for the 'open to below' look I wanted. No issues. Then I placed fencing on the upstairs landing. And this is what happened:
The frieze disappeared from the upstairs living room. I tried to reapply it and says "Nothing to Change".
I hope that's clear SimGuruJohn.
