Duplicate multicam clips crash

Needed to duplicate projects and events to new drives...

Looks like everything transferred properly, however in timeline where I have multicam clips it says missing and no thumbnail... no red that media is missing, just the word missing where clip name would be in timeline... look in event browser and multicam clip is there.... clips that were used to create multicam are there...

attach old drives and clips show media as it links itself back to old drives.... I tried just duplicating multicam clips and it crashes.... any thoughts?
