Thank you very much.
I noticed two strange things in how compiled grasshopper definitions work right now.

  1. While compiled, GH definition you attached doesn’t show geometry preview on my pc. Can you confirm that on your side also? Content Cache connected to the Synapse Bake button works ok.
  2. Adding a Get Boolean component (anywhere, it doesn’t have to be connected to anythin) to the definition changes the behaviour and:
    a) Geometry preview is now visible
    b) Synapse Bake button doesn’t work
