Funny Physics Glitch in My Game

My game involves picking up and putting down boxes, and the code I wrote to do that resulted in a pretty funny physics glitch. If you clip the box into the ground just right when you put it down, it launches you really high into the air. Also the box can completely clip through and fall into the void, so I made it teleport above the ground if that happens. Not sure whether I should fix it or leave it :)
