Quoted from Medisinyl:
I did have one other person (out of over 200) suggest an issue, then never heard back (no mention of hitting the mouth though). Otherwise, all has been positive.
Welcome to send me some photos to see if the issue can be identified.
I could never sort the issue out that I was having with the gargoyle head and removed the mod. It was not firing properly across the playfield when exiting the VUK.
