Hello @Riiskyy, looks like you encountered #5901 as a side effect of "Fixed an issue with invalid Steam Play tool selections if user had previously opted in to enable Steam Play for all titles. (Note: this will cause a one-time reset of all Steam Play global and per-app selections to the default state)." from the 2019-01-18 Steam client beta update, which went into the stable client release.
Closing in favor of the existing report.
Nothing extracted yet.
Your system information
Please describe your issue in as much detail as possible:
I spent an evening playing Monster Hunter World through steam play. I quit the game to go to bed, Steam tells me there is an update and asks me to restart steam. I restart steam and then shut down the computer. The next day I wake up and start up the PC, when I open up Steam I cannot find Monster Hunter World. I found that the "Enable Steam Play for all other titles" has been disabled, I re-enabled the setting and fired up Monster Hunter World. Instead of launching the game it starts downloading. I check
and the folder is basically empty except for graphics options, config.ini and 3 empty folders. I now have to spend a full day on my slow internet re-downloading this game and hoping that my cloud save is still there.
I tried checking
but there is no steam folder here. What happened with this update and why was my game deleted? I have CS:GO installed on Linux too and this was unaffected by the update.
