Basically: The physics engine doesn't support cutting them.
Technical: The cutter system works by raycasting the cut points, and manually placing all the vertices inside new bodies depending on which side of the raycast they fall. Since circles don't actually contain any vertices, they can't be cut.
Probably. Hopefully it will satisfy people for a while, though, because I'm definitely going to take a small break after the release since it's been such a huge load of work.

Exact steps to replicate? Everything working as expected on my end.
