Hey,
I'm having an issue where I can't complete the demoness' quest for the egg because the game thinks I have the empty beer cup despite it not appearing in my inventory. I have checked the black market many times and its never appeared (I sold a trinket as a test and it appeared there the next night).
I'm fairly sure I didn't sell it, but I remember a) trying to give it to bert immediately after the first time you need to, and also b) maybe with mispressing on it in the fuse menu at some point.
I saw a similar issue here from a little while ago, and saw the response was just to restart. I'd prefer not to, are there any other options? ( I'm waaay past where this bug would have appeared, and save will be overwritten)
Thanks!
