A great game, with very few issues however it is a struggle to actually play it.
This is because the game, when run on Proton through Steam compatibility, does not detect the mouse movement and clicks as activity.
With an almost pure lazy build, there is no need for keyboard input.
Every hour or so, the inactivity notifier shows in the left of the screen, then it is 5 minutes, 4 minutes, 3, 2 , 1 and booted out.
I use these few minutes to finish up whatever activity, stash loot into the chest, and just log in again after.
Maybe this is a forced break feature in disguise
