Each time your game is loaded, any mod with Canary support will be tested to make sure it's data wasn't lost in your save file. If any lost data is detected, Canary will warn you so you can roll back to a previous save.

Have you ever been playing your game and found that a mod appears to not be working correctly anymore, but when you report it to the mod author they tell you they can't reproduce the issue? Do you then struggle to reproduce it yourself on another save? There's a good chance you ran into a recently discovered issue where large chunks of data can be lost in your save file!
