Tweet bugs to @jjpsoftware. They do read it, even if they don't always respond. All of the bugs in your original post have already been reported. I have to say that I don't know who's answering that twitter handle, but they don't seem too receptive to suggestions.
For example, if you hit the start button during the match sequence because your kids are sleeping and you don't want the knocker to fire, the f'n game will fire it anyway if you would have matched. They actually told me this is intentional. I told them it's a ball-busting move. People have reasons for skipping it and may want it to run most of the time so turning match off isn't what we want.
If you collect BOB and SIM card right around the same moment, it will not give you credit for the SIM card even though both the SIM card hole and BOB have their own optos in the subway so the game DOES know you hit both (one ball will pass BOB opto, two balls will pass SIM opto). It rubbed me the wrong way that they kinda brushed off this bug.
The cell phone hole will not give you credit if there's a ball in it from one of the other holes. As this is a major shot in the game, it should have been designed like the swamp in TAF so you can hit it while there is a ball in there from the subway and it gives you credit. But NOPE. Big design flaw there, and it's physical so no fixing that.
I've had the black screen unresponsive issue while idle for 5 mins in test mode. Same as your issue but in test mode, not attract mode.
Coils fire in test mode without the coin door closed. They told me some jibberish about only having to cut 70v and that 20v is still live in test mode. I thought the coils ran on higher current than 20v....and if not, then what exactly are they cutting power to when coin door is open normally?? Why bother cutting "high power" if the high power stuff still runs? And....perhaps say so on the screen so some unsuspecting owner doesn't get jabbed with a coil unexpectedly. Big liability issue here. Very surprised.
Attack continues after multiball ends. JJP said that's to allow you to get the super jackpot...but it also takes out your flipper if you don't get it. If they wanted to add a 3-5 sec compensation time, they could behind the scenes as is done on every other game's jackpot-after-multiball-ends.
