Hi, thanks for the clarification.
We've tried to reproduce your issue today, and are unfortunately unable to do so. Current snapshots seem to reload correctly between sessions.
One thing to check – when you save current snapshots, you need to then resave the preset before navigating to another preset. Otherwise the current snapshot settings will be blown away, and revert back to the previous current snapshot settings when the preset is reloaded. Is it possible that when you save current snapshots, you're then navigating to other presets before resaving the preset?
That said, if you don't change presets, but save/reload the session, the current snapshots should still exist.
If you still believe there is a bug, then please send a test session to firstname.lastname@example.org exemplifying the issue, and reference this post.
