Hello Pro, the log can only record choices while you have my mod installed. So if you installed the mod and then continued an ongoing playthrough, the log won't know what happened before. That's why I provided the bonus WT, so you can look over the decisions you made earlier.
Also, the log will NOT record any choices you make that are either optimal or insignificant. These would just add clutter for little benefit. So if your log is mostly empty that's a good sign!
If you're unsure whether everything works as intended, just make an obviously bad decision and check whether it shows up in the log! You can then roll that decision back afterwards or just load a save. Hope this helps!
