### Summary - Removes old death packet that isn't used. Doubtful this causes issues with clients that are v4+. - Removes duplicate incoming packets. Again, probably to fix some old client issues, doubtful it affects clients v4+. - Fixes setting serials and entities in props/commands. Note: Disabled setting `Parent` since the new sector code has issues. We shouldn't rely on it anyway! - Reverts a recent change to healthbars that should not have been made. Oops!
