All the mode music is shared with the background music, except for Aces High.

Here's a weird one that I've reproduced twice, last did it on 1.05.

In Cyborg Multiball:
-Have outlane revives lit
-Light cyborg jackpot
-Drain the extra balls in play
-A 10 second countdown starts to collect the jackpot
-Drain down an outlane and get revived
-Another countdown starts and plays concurrently with the one that was already running. Eg: 10, 3, 9, 2, 8, 1...

Pro

Pro 1.06

Got the mummy multiball total stuck up on the screen for at least 20 seconds until I locked a ball. It took a few seconds to start the trooper lock animation after locking it.

There was a lot going on and I think the game got confused. Was in Fear of the Dark, started mummy, finished the mode right after ending mummy. It was on the mummy total screen when I shot the soul shard, but it never displayed the soul shard animation. I don't think it showed the Fear of the Dark total screen at all.

Yes.

They aren't consistent with their code package filenames, why not switch up the language too?

If you're not in a rush to update then I'd give it a week and see if there's a bugfix release. If you really want the new features and don't mind the update process then go ahead.

I've had it change the song on me a few times after plunging but before the playfield is validated. Maybe they moved song selection off the shooter lane switch to playfield validation?

Here's a new one:
Was in Cyborg Multiball down to 1 ball, collected the ramp, hurry up to collect the orb, got it, auto-launched another ball into play, then it turned ball save on & killed the flippers, ended Cyborg, and launched 1 ball into back into play.

Nope. Pro 1.06. I just have a knack for making Cyborg Multiball do wierd things.

Pro 1.06 - During Trooper Multiball, the lightshow for one of the shots got the GI stuck in a half-on state. This persisted through and after the end of the game, including Fear of the Dark mode. When this happens the bottom LEDs on the slings and the LEDs behind the ? and below the launch gate are off.

I've had this happen 2 or 3 times since I've owned the machine - seems like the game does not totally refresh the state of the GI LEDs at any point and relies on what it thinks is illuminated.

Yeah, you'd think they'd check each switch registered correctly. Occasionally someone mixes up a wire or connector. I know of a Batman '66 that's been on location for 2 years that has two of the lane switches swapped. Op has never bothered to fix it (or update the game since buying it).
