Curious if anyone else has run into this as googling it didn't give me any results. Occasionally on Star World 3 after jumping hitting the P switch then tossing a block at the Lakitu the block will completely phase through him. This will either result in him being unkillable (which only happened once) or in my being unable to pickup blocks for the remainder of the level.

Just thought it was odd.

This happened to me on the Wii VC and on the Snes9x 1.60 Emu.
