Sorry, I can't find this information anywhere. For some reason, when I'm editing from one sequence into another, my linked video and audio become unlinked after I insert the content, and I have to manually relink it. I can't understand why this is happening. There are a few nested sequences that I am editing from in the Source Monitor, but it seems like this is happening on simple clips as well. Obviously I've got Linked Selection toggled in the timeline. Please let me know if anyone has any ideas on how to fix this.
