When you drag the new clip top the viewer to add it to the old multi-clip, you should get two options, add to multi-clip and add to multi-clip affiliates. Try the affiliates option, I have had some luck with it but haven’t used it enough to figure out when and why it did work and when it didn’t.

Are you working from firewire drives?
Is it a huge project spread out over many drives?
Are both editors working on the same project at the same time or is only one working on it at a time?

Our set up is simple and it may not be of help but we keep all the media for one episode on one or two drives and don’t mix the media with any other episode. That is, they’re dedicated to just that episode for the duration of offline.
We save the project to the Episode media drive and they’re backed up by the assistants every evening to an FTP server offsite. The project is ingested on any of two systems by two assistants and not always by the same person for the whole episode.

Make sure you have “ignore permissions” set for all your media drives. I think this is default on firewire drives but our process when new drives arrive is to format the drives writing Zeros to the whole drive, journaling off.

I guess you probably have more complex needs then that but it’s a baseline to start from.

There are other tricks like naming any immovable media drives the same name on both systems and keeping the capture scratch and render folders synced between the two systems so that moving the project doesn’t require a ton of relinking.
