On that particular save? No to both. I do have A NG+ run I'm working on. But that save is kept in a completely different folder when not in use. My guesses are either coins and flames got added to the game in a patch but the fox sense "list" didn't get updated, it's erroneously "counting" some other items it's not supposed to, 15 year old laptop spaghetti code, or some other 4th thing.
Oh you're not started to play from version 1.1.5.
Yeah than that definitely could happen. Some variable numbers can get mixed up when saves are transfered over mutiple version since I often added, fixed and adjusted stuff.
There might also be some other kind of bug, but that would be hard to check myself without playing the entire game on a fresh new save file to to verify myself.
Thanks for the report I will keep that in mind and someday replay the game to see if there is some kind of bug.
