* The ladder out of the Wither Pit doesn't seem to be working.
* When you ask the merchant in the Pit to show his ordinary selection, your inventory pops up, and the trade window either doesn't open or closes immediately. I believe this might be because the store is scripted to show at a dialogue node that can actually be responded to with [End dialogue], overriding the trade/barter window.
Seems the ladder was blocked when the additional NPCs were down there. It still is pretty tricky to get up, though.
Should be fixed.
