Floor plate not quite flush

[TARNATION !!!]

I was playing with the frame and trigger plate on 108603. Both are clean. When the plate is seated into the frame, a small area at the "doll's head" portion of the plate rides noticeably proud of the frame. I'm guessing something is slightly warped, most likely the trigger plate head. It seats flush everywhere else along the full fit. Has anyone "repaired" something like that? Gentle smacking with a small rubber hammer does not change anything.

I could just live with it, but I'd rather the entire piece fit flush.

Thoughts??

Thanks,
Jack
