The saved game folder used by ONI switches between two alternative folders (listed below) with no apparent reason why. Sometimes it'll start with one, then switch to the other.
Every time I start the game, I have to carefully evaluate if the game I'm looking at is the most recent saved game. If it's not, I sometimes have to go find the saved game in the other folder and copy it over.
This is really aggravating, since I have to be really cautious about starting my game, and I have no idea why this is happening.
Most of the time it'll start out showing the wrong saved game, and then update in a few seconds to the correct saved game, but sometimes it never updates.
The two save locations are in my documents (C:\Users\[username]\Documents\Klei\OxygenNotIncluded\save_files\auto_save), and in the steam app for ONI on my second hard drive (F:\Games\Steam\steamapps\common\OxygenNotIncluded\Klei\OxygenNotIncluded\save_files\auto_save).
On a side note (just in case it's related),my mods all disable every time I start the game, and I don't know why.
Steps to Reproduce
Start the game. Look at the "resume" saved game listed. Or click the load button, and see what files are listed.
