Packaging Error: archetype is not the CDO nor a default subobject of my class

Development Programming & Scripting

Solution/Cause:

I narrowed the problem down by going back several commits. At one point I added the following lines to the DefaultEngine.ini file, cause I was annoyed by too much output:

DefaultEngine.ini 
[Core.Log]
Global=Warning

If I comment out the Global=Warning line, all works again; if I leave it in: same errors… strange.

Could this be explained?
