Getting kicked out of game during friend visits.

I just did my neighbor visits and didn't get kicked out once. On the other hand it was horribly, horribly, HORRIBLY slow moving from one town to the next, so I closed the games, pulled up the app managers and swiped them away, then turned off my devices for about 15 seconds. When I went back in my transition speed was WAY faster. Try doing that and see if it helps.
