Steam keeps re-downloading Destiny 2

[Spacecraft]

So this has happened three times to me now. I'll boot in to Windows (I dual boot windows and linux) and it seems Steam is re-downloading Destiny 2. I booted in to windows last night around 9PM did some work and left the computer for several hours. When I came back I rebooted my computer in to Linux. I opened up my routers page to check traffic usage and there was 80GB downloaded over web file transfer (which is how the router categorizes Steam download traffic).

The only other game I have in my Steam directory right now is cube world which is a couple hundred MB.

I do not have Steam set to launch automatically in Linux, nor do I have my Windows drive set to auto mount so even if Steam had launched it wouldn't have seen any installed games it felt it needed to download or update.

My Windows install is completely clean except installs for Steam, Battle.net launcher which is currently only managing wow classic (which is ~3-4GB), my razer software, and spotify. The only things that were running when I left the PC were Steam and the razer software.

Destiny 2 and Cubeworld are both set to NOT auto update. How is this happening?

Was Steam closed properly before you shut down Windows?

Usually happens when you incorrectly exit Steam.

Installed games are appearing as uninstalled

I just told the PC to reboot and it closed steam, like I've done a million times before. I am wondering if it has anything to do with my system time being out of wack when I boot from linux to windows. I have to resync the windows time after having been in Linux, and I know that incorrect system time screws with programs sometimes. How that would lead to Steam redownloading the game is beyond me, but I've seen stranger things happen.

Yeah, that's not closing Steam properly. If Windows things it takes Steam too long to close properly, it is simply terminated, which can lead to data corruption.
Close Steam properly and it won't happen again.

It's so weird this is happening now. My steam account is 16 years old, and I've never once closed steam manually before shutting down my PC lol. For years and years I kept maybe 100 games installed across my main SSD and my storage HDD and never saw this happen. But good to know there's a known cause for this, and it has a simple fix.
