I tried searching for this, but I honestly don't even know what to search for:
I played this a while yesterday, booted it up today again. First thing I noticed was the fact that my money was set back to $100 and then I checked my character stats, and indeed, they were back to their base levels from the start of the game (all of them, including relationship stats with characters). This is true for my hard-save and all my auto-saves.
Is this a common bug? Is there a way to avoid it? Should I avoid using hard-saves and only use the auto-saves? Should I avoid reloading all together?

All missions have rolled back as well; Julia wishes to help Kate with her shyness again, if I find wine at work, Lien starts here gossip mission from the start again. Seems true for most things, like the game has restarted from day 1, but it's day 15.

Where are the save files stored? I'm not re-doing all the grind I did yesterday, so I guess some quick save file edits can help me out, no? Found it.
