In a certain project, if I select a group of clips and move them in the timeline, or if I close a gap, or even perform a roll or slip edit, some of the clips "disapear"! When I try to undo... all of the clips except the new invisible one snaop back. There is a new hole in my timeline! Sometimes I can click where the clip used to be and pull them out of thin air! Other times I cannot grab them, and if they were a rendered clip, the render file stays intact.... even if I put a new clip in the same spot of the sequence. It will play the referenced "invisible" render clip!
Anyone else?
