I will be able to test this tomorrow as I am working from home today and unfortunately my pc here cannot handle the engine well. I believe I was running it on 4.7.P7 but I’ll run several tests to be certain. Thank you for your continued patience.
The issue is fixed in 4.7p8. I checked convert-in-place directly from fresh 4.6.1 creation.
I did open up the non-working existing project, some where OK. Some not. To fix the non working ones I had to zero out the Transform->Rotation (the Endpoint was way off where it should be).
