If I make a new Graphic Override for Walls using a rule that uses the Composite the wall is made with, it does not work.
If I do the same for Slabs or Columns but not using their Composite it does work.
Pre AC21 Graphic Overrides that I had set up in AC20 and uses the Wall's Composite they do work on the Walls but if I add a new rule (which uses the walls composite) then the new Rule will not work.
If I duplicate a previous rule that works the new rule based off the duplicated rule, does not work
If I make a new rule from scratch it still does not work
On the bright side I go on holiday tonight for 3 weeks, so it will be somebody else's problem tomorrow
