Remove Track That Could Not Be Connected

I’m working with big projects (more than 600 tracks, more than 500MB Cubase project). Many times when loading a saved Cubase project, it says “Remove Track That Could Not Be Connected,” and all ports and VST Intruments Connections are lost. How to fix this project? Creating new VST ports everytimes is nonsense …
