I just tested on two maps and shot my arrows at very high angles, beyond 45 degrees. They seem not to come all the way down to ground and vanish at some point. They didn't go through the 'sky ceiling' because I saw them coming down. Even arrows that were shot as high of an angle as you could didn't come back all the way down. Is this a bug or a feature? I was using strong bow with barbed arrows and longbow with bodkins.
