Found a similar bug in snapshots. After loading the snapshot in Copyholder (I used right click>view on Copyholder), then closing Copyholder , it will crash if you try to load it again in Copyholder .
Thanks for the catch! This has been filed as well. In future, it would be helpful if instead of replying to another bug you created a new post, that way it is easier for other users to find.
I’ve split this into a new topic.
