Looks correct from my end for Turns 23-26. We don't have any data prior to that, IIRC, so everything looks good.Please verify the last few turns' worth of successful tailing to let me know.
That's actually very interesting... If you take evasive action, you shouldn't be able to "stay on target." Or to put it differently, if you got your hands full evading a missile, you should definitely lose your tailing result.
I agree on this and think it should be a rule for the next version of the game (tailing and evasion should be exclusive of one another, or if you do one you can't do the other).
Got some RL to take care of; hopefully I'll be able to stop holding up the works later today.
