24 instances! Well, yes, I can sort of imagine VideoCopilot didn’t QA for that. All on one layer suggests to me that you might not be using Saber the way it was intended.
I am sorry for you that it corrupted your project, there’s almost nothing more disheartening than that. I’ve become a bit of an evangelicalist for cloud backups. I use Google Drive to backup my project folders and just lay week screwed up by overwriting source footage. Fortunately because I had it backed up, I was able to retrieve the file.
When/If you recreate your project, post a screenshot here and we can see if there is any way to cut down the number Sabers.
