I’ve had the problem too. What worries me is that if render files aren’t updating, then how do you know you’re watching the most current changes. ie You’re going to notice a deleted clip popping up, but how do you know there isn’t a more subtle filter that you deleted still on a clip. And then when you go to create a movie, is it in the final product?
Is the safe advice to delete all render files before creating any movies?
