So m_valuesCount == 0 here (set in constructor of Object and overwritten by inherited classes constructors? so should not happen for Creatures, Players etc?)? Why? Where should I search for the reason of this crash? I would like to report (if really connected to clean core code) and learn how to fix this

m_valuesCount == 0 meaning that object or detroyed, or not exist or pointer point to random memory, or object fields corrupted by some code.
