Ok so here's the early stages of my game engine. My Character knows if he's holding something and what it is, and the objects know if they're being held and by whom. My problem is that on the death of either entity they both seem to remember this things. I've even overridden the Kill function to forget, but it doesn't. It comes out as some glitchy mess. Death sometimes seems to toggle being able to pick things up... I'm lost.
