So every now and then when I stop to save the game it just crashes and shuts down. It only happens sometimes and unpredicatbly so. Any way to fix this?

Addendunm: It also won't let me simply restart the game after such a crash. I have to quit GOG Galaxy first, thens tart it up again, then it tells me to re-install the game. It is still installed of course, and it does start up when clicking install. Maybe my game file is courrpted somehow? Should I just de-install & re-install completely?

Addendum 2: Welp, now Gog Galaxy told me that it couldn't find the files at all. The play button is greyed out, the manage installation options are all greyed out, can't click anything. I would attach a screenshot, but trying to upload the file to this post tells me wrong file format, even tho it's just a jpg... I think GOG Galaxy does not like me?

Anyway, de-installed the game via windows, now in the process of re-installing. I'll be back in 5 hours or so.

Addendum 3: Well the attachment works now. Ah yes you gotta have the file extensions in lower case letters or it won't work, how silly of me to not know that. :V

Hopefully final Addendum: It seems to be running fine now, have not had any more crashes thus far, even after beating a boss and several cutscenes. Seems to really have been a case of a faulty installation. False alarm.
