So after spending 2 hours recording a song with a few tracks, I just went back to re-record a guitar track. I finish and Garageband then pops up a message saying analyzing, freezes for a second, comes back and all my tracks except for the new one I just laid down are gone. The drum loops I was using are scattered over multiple tracks. I tried looking for package contents in the song file, but nothing was there. Garageband then crashed a few minutes later while I was trying to find an answer to what happened. Not a huge deal, but I'm just wondering if there is a way to prevent this in the future and if there is a way to recover the tracks? Luckily I had bounced out a rough mp3 earlier so I have some record of the song.
