The previous build introduced a new bug. Enemies in the overworld would spawn just a bit higher up than they were supposed to. It looked the same in-game, since you are seeing everything from the top down, but they could not properly interact with the player. So while you could fight them, they could not fight you back, and you could not search their remains after a fight.
This should all be working now. However, if you saved a game in the previous build, you may have to enter a dungeon and return to the overworld in order to reset the enemy positions.
