That's great that you are back up. If you have tracks that are pretty much done, I like to freeze them and then I can always unfreeze them if needed. I hate waiting for loading and with most of my project frozen it loads in a few seconds. I know everyone has different workflows but maybe it can help. I even made some scripts to help frozen tracks be obvious. Best of luck.
