How do I pivot sprite around origin point?

I know it's supposed to do it automatically, but for some reason it seems like the origin point resets.

I made the game by editing the jumper demo, maybe that's it, maybe the demo was made before origin point. I have no idea.

Arrow keys to pivot. It's supposed to pivot by the bottom, but it does it by the middle. The little ball I attached to the origin point to find out where the game thinks it is.

Okay, I figured it out.

Physics behaviour doesn't follow the "rotate by origin point" rule. Seems fitting for the physics behaviour's DIY approach so I dunno if this is a bug or not.
