I noticed that #3319 is supposed to fix overdue snapshots not automatically running. And it does. However, overdue snapshots do not run when the computer was put to sleep (with Kopia running of course) before the designated snapshot time and woken from sleep after the snapshot was supposed to have been run. Instead, Kopia needs to be restarted in order for the missed snapshot to be automatically run.

For further info, I am running Kopia 0.15.0 on Kubuntu 23.10.
