Snapshot is having problems with automatic schedules

I have Snapshot installed on many of my sites, but about half are having problems with the weekly scheduled backup at Sunday at midnight.

The problem isn’t specific to one server either. Websites even on the same server, and half will have the problem.

Manual seems to always work. Let me know what information you need.

I also saw an update since I scheduled them last week. Do you think that that will help this issue? Thanks.
