I have a big project file that contains many tracks of different guitars playing the same passages, as a tone comparison reference master file. At some point recently, the project will no longer save any changes to the track folders state (which ones are collapsed and which ones are open), and I've added many new tracks to it since then and each time I have new track folders states that should have been saved with the new recordings, but they weren't. So every time I open that project, all the new recordings I've made are there, but the track folders state stay the same as when the glitch started happening. It doesn't matter of I collapse the folders that are open and open the ones that collapsed and then save--it just reverts back to that one state. What can I do? Clear out a cache of some kind? Rebuild the track folders saved state some how so it'll start updating with each new save?
