Neighbours bakery turns green when trying to tip

[pib83]

I have had this problem for a while now, I can manage to tip a few neighbours then I'll go into the next neighbour and the screen will turn green or it will continue showing the processing screen. I've got an iPhone 3gs version 5.1 and my BS is version 1.4

It sometimes happpens to my bakery- the screen goes black and exits the game. You should contact TL: support@teamlava.com
