I just tried out the nested timeline feature. I had a long project with lots of markers to show good bits of interview etc. I created a nested timeline, then when I switched back to the parent project and all my markers had vanished. They are still selected to be viewed, and if I create more, the numbering starts from 1 again, so they are just not there. I sadly saved it before I spotted the problem so it looks like I'll just have to go through the whole project and create all the markers again. Is that a bug or deliberate??
