You have gotten the "Groundhog day" bug. The game is unable to save all your progress and when you load the game again it loads parts of your old progress.
If you believe it is caused by mods, you can look for more information about it here: https://answers.ea.com/t5/Game-and-Mod-CC-Issues/Mod-Related-Game-doesn-t-save-Time-reset-on-transition-Part/td-p/11676785 this is where it was first discovered through a mod which we can't talk about here on the forums, the mod creator added a workaround.

It seems to be related to how the game is saving outfit data. And the worst part is that it seems to be very difficult to get rid of once you have it in your save. Make a backup of your old saves and if you are using mods, make sure that they are up to date.
