It happened on try again and going through the menu, I have been unable to reproduce it after closing and reopening tho. If I recall correctly it happened while dragging a Potion around, probably over another Potion.
The only TextFiles created are Player and Player-Prev, do you mean those? I'll do a couple of Runs over the Day, trying to reproduce the Issue.
Sorry I can't help more on that, I don't fully know what I did when it happened, or why, or how to reliably reproduce it at this Point.
