Steam keeps uninstalling my games when I turn off my PC, help!?

[Justin_760]

I thought this was a bug with Pillars of Eternity 2 at first, because that game was continually being removed from my library whenever Id turn off my PC. When Id boot up steam again it would be greyed out in my library, with the only option being install despite the files still being in steamapps folder.

But it started happening with Battletech and Evil Within 2, which can only mean its a problem with Steam, NOT the specific games. Has anyone encountered or heard of this bug before? Or know of a fix?

To reiterate, when I turn my PC on, whatever game I was last playing before shutting down will be shown in library as not installed, necessitating me to reinstall the damn thing which takes around 30min every time. Ive checked and the files didnt actually get removed/uninstalled, it seems to be a problem with steam not detecting files but its become burdensome and irritating as it happens every day now.

Close Steam with
Top left corner small Steam text > Quit

If you shutown pc without closing Steam the installation files may become corrupt and lead to such errors
