Confirmed bug. Happened to me this week. Had Trooper going. Dual simultaneous drains with Revive on both. No balls saved.

^ This. As bad as Stern's fake knocker has been in the past, the one on Iron Maiden is definitely the closest sounding to a real knocker. I turn it off by default because I play late at night and don't want to wake people, but I tested it a bunch of times in diag and it sounds good (for a fake knocker), to be honest. Much better than past efforts.

Has anyone experienced any non-registering with the right outlane REVIVE after the 1.02 update? I had a few games where REVIVE was lit, and the ball drained right and the switch did not register. It did this multiple times over a few games. I took the glass off, went into switch test and ran balls down the lane...each one registered every time regardless of speed. So it can't be the switch, but nobody else is reporting it here. Just curious. There is a bug where double drains with REVIVE don't register and give you the balls back, but this is just a single drain to the right outlane.

The Definitive Guide to Fixing the Plunger Not Making the Loop

First we want to make access and fast adjustments quick and simple:

(Less than 5 minutes to do the following)

1. Remove the nut and washer from the right ramp wireform at the slingshot.
2. Remove the screw attaching the wireform further up. Then remove the wireform.
3. Remove the nut holding the right plastic (the one with the blue flasher).
4. Remove the bolt further up the plastic (the one that held the wireform on) by simply unscrewing it.
5. Unplug the flasher under the game and remove the plastic assembly.

Now we have easy access to make rapid adjustments after each test.

(Less than 5 minutes to do the following)

1. Unscrew the two screws at the plunger that hold the bubble level on.
2. Unscrew the nut under the playfield that attaches the ball guide to the playfield.
3. Unscrew the right side screw from the exit gate and rotate it out of the way.
4. Unscrew the hex screw next to the bulb (red on premium/le, white on pro) at the end of the ball guide. Carefully lift out the ball guide.

Now you make adjustments. You'll find the rail is easily bendable so adjustments should be subtle. IMPORTANT: The ball trajectory is affected not just by the curve at the very end of the ball guide but by the slight curve further down as well so where you bend it matters. I suggest working towards the end.

Now all you have to do is adjust, place the ball guide back in and screw in just the hex nut next to the bulb.

Next, in attract mode drop a ball in the plunger and let it shoot it. No good? Unscrew, readjust, pop it back in.

Good? Test it at least 10 times. Good? Awesome. Now test the manual plunger by doing the same thing but shooting the ball manually before the auto plunger does. If manual is no good but auto is, you've bent the ramp unevenly. The top half is slightly different than the bottom. Be sure to adjust so it's bent evenly top to bottom.

Each adjustment cycle should take less than 30 seconds to test. It took me 6 cycles and I've got it perfect. 20 out of 20 after previously getting about 70%.

Then just put everything back in the reverse order. This whole process should take you less than 30 mins and should work for everyone.
