Oh yes, I have seen that happen too. I even know the reason and am doing some things to have it happen less often, but it still does. When a physics collision happens (an arrow hits a bot), I get a callback, and can then tell the bot he got hit for example. The problem is, the callback happens after the collision/physics calculations have finished, and sometimes with very fast moving objects, this means the arrow can move a little (or a lot in this image haha) before I can do anything. So the arrow actually hit the bots upper chest I suppose and got stuck, but before that it moved more than I would like it to. I really don't know how to fix this currently, but it is on the list of things I really want to change! Thanks for the feedback, I wasnt sure if this was happening to anyone else actually so that's really good to know
