You did something to the collision box of Tree log. Now when dropping Tree log down half the time character gets low-key stuck (like being on a ridge -- can't interact with objects until you click to step away from dropped log).
Also, remove or fix collision box of new sled: it's painfully unusable because it can't be dropped near objects and after it's dropped you end up in the middle of its' collision box, but not quite in the middle -- you can pass to one side but get stuck trying to move to other side.
