I don’t know if this is a bug but when you have friends of friends appear, are you not able to invite them to activities? The activity window comes up over top of them and I can’t see them to drag them to an activity, is that what is suppossed to happen?

you should still be able to see them, it sounds like you are referring to the solo actiivties, like watching TV, which comes up in the middle of the screen. To invite people, you need the social activities, which is a separate button and a separate window to the left of the screen,
I think thats what you mean?
