0% score

What's the matter with Drifter getting 0% score against a lot of bots?

I ran some battles locally against it and I could only reproduce ~35% score against Knight, even though it got 0% against it in two releases in RR.

My observations are similar: in GUI it is ok. I suspect it is robocode bug which is triggered either by luck of GUI or some other measures. I think MoxieBot has similar issues, though in GUI you see sporadic complains and radar lock in the wrong direction.
