Quoted from WinterMillennium:

Hi folks,
Also having an issue with my X-Files... when a ball is launched, it gets stuck in the VUK mechanism until ball search begins, then gets launched. Also causes issues with multiball, with all balls getting lodged there and being released one by one by ball search. This doesn't seem to happen when the ball is being returned to the VUK from the filing cabinet. Seems like it isn't recognising when a ball enters from the shooter lane? Any ideas?

Quoted from V_piscopo:

What are the rotateable arms on the head for? Was it for a factory topper?

Quoted from play_pinball:

Anyone have any recommendations of what to check out for an odd file cabinet issue? Everything works fine in diagnostics and testing. It seems to know it’s location at all times but it just isn’t resetting properly after a multiball. Each time you activate the opto it will push it back up a little bit until it’s finally all the way up. Video to show what I mean:
