Hey kindeyegames, I'm not sure if you saw my reply to your request of a project file containing the bugs I had reported previously. Since the response was pretty deep in the thread, you may have missed it, but I did manage to put together a demo for you showcasing the issues I mentioned back then.
Here's the link to the demo just in case you didn't see it:
