I’m trying to read information out of the InstanceDefinitionTable to sort through blocks and export them. I can access all other information in the file (materials, layers, views etc.etc.) but the instance definitions only return a NoneType object. The instance references themselves refer to the correct UUID (ParentIdefId).
I attached the test files if anyone wants to give it a try. I ran it from a python virtualenv as well as from the blender python console and got the same results, as well as on my laptop. I also checked Rh5 and Rh6 files and tried a clean file without any plugin data etc.
I wonder if this is a bug or if I am missing something substantial?
