I received #91 today. The metal base does not lie flat to the top of the pinball but it cannot be seen from the player position. I tried a game as R2-D2, it integrated nicely. No need to video that since it was already done. I did video turning it on the first time. Partly to provide a video of the proper sequence of events when the topper is first installed and the nodes are loaded. And also to film in case it did not go smoothly I would have video to show what happened. Luckily it installed properly.
