I look at exploits on a regular basis, but it competes with bug fixing, optimizing, cleaning up old stuff, updating engine/3rd party code, balance and new features. Yesterday I started redoing how AI walks on ladders due to the bouncy ladder exploit. Legacy code basically just shoved the AI up the ladder. Now they can walk and stand on them like a player can. Hopefully that will be ready for testing today, but may not be released until after stable.
The bandits will just nerd pole up to your roof, bust out the wall and rob you blind.
Easy. "Is that a bear over there?", then they teleport while you are looking away.
