[Bug] Sheldon Skaggs and "Phantom Units"

Okay, so the "Sheldon Sgaggs" unit has a pretty severe bug. It has a ability that throws the units of the row it's placed to random rows. The problem is, it always "stacks" units. Meaning two units goes top of each other. And when the round ends, one of the stacked units stay on the board, just the card though, no value. Meaning when next round starts, there can be a 6 point unit on the table, but it doesn't give value to the total score. It also stays there for the rest of the game. If you but unit on the same row than it, they stack, and it looks bugged.

Reason I'm bringing this up: I've have had multiple players trying to harm the "phantom unit", even though it does not exist. It's making players make mistakes, and I'm starting to fear someone is going to report me for doing something against the rules, even though it's out of my control.
