There are some tables that will currently show some minor issues with this, so please if you find something minor (like on MB the ball does not make it to the top due to the shooter lane needing a minor correction, or Humpty Dumpty's 5 balls getting wildly sucked into the apron, as they are created with slight overlap in the beginning), try to fix it on your own and retry with that (if the correction makes sense/is tiny!). Due to the removal of several not-so-physically-correct-ball-teleporting-hacks in the core, this build is now much more fragile if balls are created in too tight spaces or if kickers are not correct size, etc.
Otherwise please report major issues in here, as Fuzzel said. There shouldn't be any, but you guys are always good at finding such things, right? 
Also please have an eye on ball behavior on flippers, plunger and other places where the ball(s) can rest, as now also the old ball spin limit is not needed anymore (at least from my experiments).
Would also be good to know how rubbers behave now, i had at least the impression its much better, even if not using height 25.
