My wife and I got machine #414 just before Thanksgiving! It's been a blast so far, also pretty fun to figure out all the little quirks of owning a pinball machine. Spooky support has been awesome for the couple things we contacted them about (had sound issues, turns out the audio cable was just loose from shipping; had one of the slings get 'haunted' and start randomly knocking, turns out we just needed to adjust the leaf sensor a little...stuff that is probably obvious to anybody who's owned a machine before).
We also occasionally have a ball get stuck next to the monster, raising him up a tad from the settings menu seemed to prevent it but had him pretty much touching the top edge of the case which I read was bad, so we lowered him a tad; ball still gets stuck occasionally after a game, but just going into the operator menu signals the monster to raise up a little more which unsticks the ball. Very simple workaround.
The thing we haven't been able to figure out yet is, we're now getting 2 balls loaded into the shooter occasionally (about once every 6-8 balls). Doesn't seem to hurt anything, it's kind of like a "free" multiball. I've noticed a few others with this issue, but any concrete leads on how to fix it (in terms a newbie can understand)?
