Ohhh so it's indeed a bug that's introduced recently! It's much easier to find it with the context you just provided.
So the game will end in a draw after 50 turns has elapsed, there's a bulletpoint in the help page and I figured player will discover it the first time anyways. The purpose is to prevent overly defensive playing and the endless loop of "damage - heal - damage - heal" which is NOT FUN.
I fixed it and also added a confirmation dialog whenever user clicks Exit to Title or Reset Entire Run.
