Did either of you use File>Save as>Support Assets>Save Modified Assets?
I think you might be on to something. I had noticed in 4.0 that the Save Modified Assets placed the files in the main Genesis folder instead of the Author/Product folder. 4.0 didn’t seem to care about that most of the time, but it would apply those morphs to the defualt genesis if there were values applied at save though.
Even if you never used the Save Modified Assets, if there are additional files in that folder other than the default files this could be the problem.
Could it be that 4.5 see’s those files and thinks it needs to load them with a value applied?
Maybe check the Genesis folder and see if those morph files are listed there instead of in the Author/Product folders. I’m not at my DS comp right now so I don’t recall the exact path or which files should be there in the main Genesis folder.
Anyway, it’s a thought, I’m not sure if it is the root of the problem though…
