For the second time now, I've had a crash on the standalone GOG version of the game. The game freezes and eventually crashes. Both times, it happened when quickly selecting Leave on the god panel after taking a boon (first time was with Binlor, don't remember which boon; this time it was Mystera, taking refreshment). I haven't been able to reproduce this intentionally, so unfortunately it only seems to happen in the middle of a fun run
(and of course, it's possible that 'quickly leaving the altar screen' is not actually related to the cause of the crash, but it's all I've got to go on right now).
The fact that when I play the GOG version of the game I'm on a computer which always has a bunch of useless stuff running in the background affecting performance probably doesn't help, but I figured I ought to report this anyway. I haven't had any similar occurrences on the steam or browser version on my own computer.
Here's a screenshot of the specific state the game froze in when happened for the second time. I notice that the piety counter on the altar panel is not updated whereas the piety counter on the character panel already is; no idea if it's relevant, but thought I'd bring it up just in case:
Hope this is helpful in some way!
