I think you can reach the devs more easily if you join Discord using the in-game Community link. You can post save files and crash logs. That's something I found out only after the fact.
I actually had a pretty bad bug after the new patch. If I enter Floor 15, I have to reload the save after each turn cycle to act again. Bug does not cause trouble if I backtrack to Floor 14. Anyway, I posted files/logs on Discord. Steam got another patch today, so it might be the patch after that or beyond for stuff to process.
