Floating Cube Glitch

A glitch I encountered whilst messing around in the puzzle creator. The reflection cube remains floating in mid-air when the other cube is fizzled. Seems to only affect reflection cubes with an active laser connection

Apparently it's a known glitch in the puzzle making community
