Strange VIM conversion and break down upon Source Distribution build

[X___]

I have a large project with many libraries which I am trying to release as a Source Distribution.

I am regularly releasing standalone executables of that project without a hitch.

However, the source distribution, once I open the top level VI in a copy of the project I place in the source distribution folder, after updating all paths to the new destination, ends up with many broken VIs.

Examining the source of the problem, it appears that it is due to many (if not all) VIMs in my project being replaced by VIs with made-up names (random series of characters.vi), and the Assert Type VIMs in those VIs being themselves replaced by similarly randomly named VIs, and broken.

I recall having read threads about some sort of incompatibility between VIMs and libraries, but since I did not have any problems with them during development (or application release), I am kind of at a loss as to what to do next...

Is there some literature I can read on the dos and don'ts of Source Distribution release and VIMs + libraries?
