Generated python code does not import properly

[nosajthenitram]

I have a main.ksy file, which imports another import_1.ksy file defining a sequence and some types. The import_1.ksy imports a common_types.ksy file, which defines some common types used in multiple places throughout the code.

When I compile the main.ksy file, I end up with references to the common_types.py in my import_1.py source but the common_types.py import is missing from the top of my generated python.
