I wonder how Timeline would react during that process!
I can help you out debug and test out : )
Don't burn out yourself on this, it's not urgent... I added a warning on Mary to ensure people keep at least the 39 version for the scene.
While VAM is closed open the Chokaphi.DecalMaker.54.var and replace the file at "\Custom\Scripts\Chokaphi\VAM_Decal_Maker\"
**Noted issues:
- This just adds shims for the JSON Float storables, but seems to fix your scene, I need to add shims for other storables
- Saving a old decal maker scene causes DecalMaker2 to duplicate itself on next load.
