Since we're on the topic, here's another oddity or bug to add to the collection; I don't think it's been described anywhere (at least, I haven't read about it anywhere). I mentioned it in November last year:
That is, ranged attacks do not remove Berserk from the attacked stack. This can be used very effectively when the AI opponent has only this one stack and cannot reach our stacks. Without Berserk, you would have to cast Blindness on this stack every round, consuming a lot of mana, but now it's free! :) I discovered this by chance at the time, and later figured out how it works, and once, I even used it intentionally.

Bug-Race took 2 days of head-scratching, but I still couldn't complete it; it's a very tricky map.)
