Hey,
I agree with you in using Clockwork ScopeIf+, which I believe contains a version of Jean-Marc’s solution.
As you’re finding you need to be careful with the OOTB ScopeIf, it is designed to be used within custom nodes…
I had graphs freeze because the unexecuted branch was being used for other nodes downstream (say you wanted a dated folder inside an undated folder, but not having the first one dated you can accidentally freeze the second create node and the whole thing stops).
Hope that’s of interest,
Mark
