Really enjoying the demo thus far.
I have had it happen more than once where a rathound will approach, and fails to attack me during combat.
I do not know whether this is more wide-spread in terms of locations or enemy types, but figured I should mention it. Most recently, I have seen this occur on at least 2 occasions in the vents on the 2nd floor of the GMS compound, though it has happened a couple other places.
