Shaft trap behavior modified. They now are one-time use and pre-knowledge of shaft traps (i.e. using them intentionally) will improve the chances of the player landing fewer levels away. Shaft traps also now randomly determine their destination. Monsters cannot follow the player through shaft traps.
