This is painfully time consuming! I've been having the crash when visiting neighbors since the event. Delete, reinstall and everything. I finally called EA a few days ago, and still no luck. They didn't seem to have any issues on their device, and suggested I try playing on another one myself. I am playing on an iPhone6 plus, and do not think for a moment that this is the cause. But that was all the EA rep could come up with.
The thing that seems to help is wait until the currency clears, Collect and absolutely no rising currency text. Then forward or backward arrow to visit another Springfield. No guarantees with that method, it still crashes after a while. That only seems to get through a few neighbor visits than rushing through without waiting to collect. I also tried disconnecting tracks from all my stations, that made no difference. I really HOPE EA fixes this bug.
