Small bug report (maybe ?) : one can apparently lose stars under certain conditions. I was farming XP at the Fire Sage stage (after having a surprising 3-Star victory on first try), and, after a getting two or three trashing (to level and evolve my non-favourites), I unexpectedly (:D) defeated him for a 2-Star victory... And saw to my surprise that I had, in fact, "lost" that Star, with the Tower rating for the room being now 2/3, and my "Remaining stars" being at -1 (for I had used all my collected stars up to that point :) ). Is it the expected behavior, or did I stumble onto a bug ?
