I've never had it stuck there, but have got I stuck a lot by the scoop on plastic that runs up the left side wall, gets tossed there from the pops.

Also I got a lot stuck on Magneto's cape.

Only place I get stuck is for a short time behind the left Nightcrawler fairly often, and every once in awhile the ball will stall on the switch slot for the Rogue shot. Always takes me FOREVER to figure out where the damn ball is on that one.

yeah, the ball cradles on the Rogue switch on occasion. I'm wondering if it's ricocheting back off of the Magneto lock wall.
