My friend and I both have dancing huds where we can invite people to dance with us. The problem is that when we stop dancing, and start up again at another time, the other person dances along with us without being invited. For example, if my friend fires up her hud and we dance for a bit, stop, and then come back later, I will start dancing along with her if she starts it up again, even though I'm no where near her (same sim though). She uses a huddles, and I use another type of random hud. Is there a special protocol that you need to use before turning off the dance? I was thinking that you had to 'remove' the person from your hud before you finished, is this correct?
