Improve Snapshot feature set

[cheribral]

I've run into situations where I've deleted a task with a custom function, and later defined something with the same name using different code. What appears to be happening is that my function is fed old state in the "restore" function, and then the process dies. I have to add code to make sure that I'm not getting someone else's data to work around this.

Is there / could there be a way to clean out old snapshot state from the database?

@cheribral Sorry for the delayed reply....

You are correct that the snapshot feature is a bit rough around the edges at this stage.

I took a minute to record some known issues with snapshots so we can prioritize getting them fixed. See #772 #773 #774 #775

I'll use this issue to track the overall progress of getting snapshots working. As for your current issue #772 is the quickest fix to avoid the issue you are having.
