Blackjack stuck in the floor

I was playing a match earlier on Spunky where I encountered a blackjack that was stuck in the floor. Half its body was below the floor with the other half above. Once I attacked it, it popped back up above ground and resumed its normal behavior.

I have no idea how this happened because I just turned the corner and there it was sticking out of the floor.

A friend of mine said the exact same thing to me just a couple hours ago. I can confirm hearing this, but I didnt see it for myself.
