I've come across an issue with some Premiere Pro projects that sometimes randomly disconnect media from the project--even when the media hasn't moved. This happens when I open up the project. I'll go to export the sequence and a couple clips have disconnected themselves from their source files. It's even more difficult in Premiere because you can't search for offline media. Instead, I've had to go through a 30 minute show to find the couple tiny clips that are offline.
What's a good way to manage this? What could be causing it? Anyone else come across this?
