Yellow exclamation mark on event - missing project file

Hello, everyone.

I woke up this morning to finish some editing on a project and when I went to FCP X the event had a yellow exclamation mark on the event. I looked inside and found that 1 of the 2 project files I had was missing.

I'm doing a wedding and I had Ceremony and Reception project files. Reception is now not there.

If I open the package contents of the Library in the Finder, I see a folder titled Reception. Is there any way to get that back into FCP X?

I tried closing the Library and opening it again and it still has the yellow exclamation.

I have Back-up turned off on this Library because FCP X interferes with my work too often backing up constantly. I do use SuperDuper to clone my entire hard drive and I was able to open the backup of the Library but it has the same Reception project missing, but no yellow exclamation mark on the event, which is weird.

I lost about an hour's worth of work, so not too big of a loss, but it's an hour I'd like back. 🙂 Any ideas will be welcome. And, yes, I turned Backup back on for this Library. 🙂

THank you
