Glad you were able to get it sorted out. The engine is still labeled as ‘experimental’, so these types of issues are pretty much expected. The instability is the price of being an early adopter. As I mentioned in my original post, one of the things that causes a lot of problems, especially if you move stuff around a lot, are redirectors. So be sure and clean those every time you go shuffle things around. It is also a good practice to start and stop the engine after doing so to make sure all that stuff gets cleaned out of memory. Good luck with your project.
Cheers,
Tony
