Well, looks like Michał Oracz wasn't sleeping too much the night before fixing the final version of rulebook
The Bio-droid from a tile is correct: a change in his shooting was one of the last we made in SMART army, after many games and discussions. At that moment Duel rulebook already existed in file. I guess Michał must have missed this change when he checked the rulebook before sending it to print. Silly, petty mistake - sorry.
