Fixed archery when projectiles are flying during a save/reload

When the player comes back from the far east some of the zones he visited and vanquished the boss in the west will be updated with a new boss (only if the previous guardian has been killed before going east). This currently affects the Moria, Old Forest, Trollshaws and Tol Falas
