I updated with hopes that crashing would be improved. I'd like to share that not only am I crashing when visiting nbrs, I now crash on my own islands. A lot...as in every few minutes. I'm almost afraid to do anything that's event related -- had purchased a 30 gold boost for LB then crashed. Gold was deducted but boost never activated. Notified tech support and was told the problem must be an unstable internet connection. It most definitely was not. Btw, I've not asked for reimbursement before.
I've gone from a daily visiting all nbr 4 egg player to occasionally 1-2 eggs. Usually my rating now is 0 -- since I just don't have enough time to revisit everyone at least twice.
If you haven't updated, I'd advise against it. I REALLY wish I hadn't.
