Ok, so I was wrong. It did not solve it.

I found a workaround. To get around the compiler looking for old compiled timelines, I simply duplicaed my scene (immersive) to a new name, pointed to it, and it worked. So, now any time I make a change, I just have to change the name of the file, almost like versioning it... immersive_v1. Thats not ideal, but it worked.
