I have a harness made of multiple sub harnesses and I have been able to hide display of individual sub harnesses by selecting them in the footer and hiding.
However, I tried to suppress a sub harness and after resuming, I no longer have the ability to hide it. The option is there and it will show the sub harness as hidden in the model tree. But the actual sub harness remains visible. This seems to be a bug, has anyone found a workaround?
note: I was able to fix by removing the cables from the subharness and immediately adding back. But then it causes errors with flattened harness so I am looking for a different solution.
