I've totally lost a project that I was working on using Logic Pro X version 10.2.0 on a MacBook Pro with OS X version 10.10.5. I last worked on the project on Dec 15, 2015, at which time I bounced it to an m4a file. I saved it dozens of times while working on it, and always loaded it from the "Open Recent" list. The project isn't listed in the Logic files. It's not in the Trash, which hasn't been emptied since before Dec 15. A search for the project in "This Mac" yields nothing. I use Time Machine on an external drive for backups; when I look back through the material saved in December and January, there's no sign of my project. I thought this wasn't supposed to happen. Would appreciate any advice I can get.
