1. "Sight" Range doesn't appear to increase beyond the initial 18.5. This is especially frustrating for "Bow" users with bows that have a range of 22, but you can only shoot 18.5. This is yet another "Bow" problem.
2. "Hearing" doesn't update it's number to reflect he bonus that it is getting from Perception, you can examine its tool tip and see it is getting a bonus from perception, but its not being displayed without you manually examining it.
3. Bow's cant shoot more then 18.5 meters even though they have a 22 meter range (see issue 1, repeating for emphasis).
4. In the very first fight in the game, its possible to get one of your characters "Stuck" in the cliff wall making them unable to participate in combat. (press against the "right" hand wall as you approach the fight trigger).
