I have seen this issue now on several systems in different projects. The bins will temporarily disappear from the project window and then reappear when you hit save. I am on Mac OSX10.6.4 running MC 5.5.3.9 on one project with 3 avids connected to Unity 5.1.3. The other project is on a different unity running 5.1.3 and MC 6.5.3 with 2 avids connected on Mac with osx 10.7.5. Not a major problem, just curious if anyone else has come accross this. I have checked the clocks on both client and server to confirm they are in sync. I have several other projects running similar configurations that have never displayed this issue.
Any help appreciated.
Thanks
