The answer to your ?s here is N N.
However, the bug is slightly mislabeled, even though that is the generally-seen manifestation. The bug is that every 3rd ball arrival into the lockup starts multiball. So normally what happens is people have 1 or 2 balls locked, then start RLM. RLM runs normally, you get a jackpot. If you had 2 balls locked, then the arrival of the jackpot ball restarts multiball (complete with ball saver (even for multiball 2+), relaunching drained ball(s), and making light jackpot lit (i.e. 20 loops to light jackpot)). If you had 1 ball locked, then you can go for the RLM super (augmented to 100M) after RLM jackpot. If you make the super shot, then at that point that will be the third arrival, and multiball will restart. With 0 balls locked, you can get jackpot-super-super then multiball restarts.
Similarly, you could have one ball locked, get a jackpot during RLM, light lock again, lock 1 ball, multiball starts. Confused yet? It's easy for me because I understand exactly why the bug is there.
An unlisted bug is "GAME RESTART WORKS," which is the adjustment that handles what the start button does. FT was the first game with this adjustment, and I can't remember if HS2 had it from day 1 or it didn't get added until L-5. At any rate, the bug is that because the car-starting noises play when you push the button in, the game doesn't start until the button is RELEASED. The standard game start logic checks to see if the button is held in, which obviously it can never be, so Game Restart=SLOW will never work.
