Usage and tool break sounds were played at 'pointed_thing.above' which can be nil if not pointing at anything or at an entity. This caused sounds to be played to all players on a server non-positionally. Fallback to player pos for sounds if 'pointed_thing.above' is nil. Replace 'pt' variable with 'pointed_thing' in 'register_tool'.
