anybody else have the walking kwik-e-mart be no longer usable

Since this event started every time I send all loose characters to the walking kwik\-e\-mart it crashes the game when I try to collect. I've since nuked and only have those characters and their buildings out \(and the characters for the event\) and it still crashes.

I never had this problem even being near the item limit \(I would get alot of lag, but the game would still play\) until this update.

Anybody else have this problem?
