I'm not really sure if this is a bug or intentional. I was playing the Accountant 1 in the area with the spiders, and the spiders seem to be nearly impossible to hit with arrows or sword. Even right on top of the spider swinging the sword I rarely can hit it, and arrows not at all. It seems like the hitbox for the spiders must be very tiny. I'm using 2.10 64bit linux version.
