Forced update but not playing

Just thought I'd let you know how playing has gone. I opened my tunnel 2 hours ago and have been playing since. I haven't moved any buildings over or stored any and as of now I haven't lost donuts. I've also exited the app and come back in, I've visited my neighbours and still haven't lost donuts. I haven't spent any donuts tho, so I dunno if that's a trigger. I play on an iPad Air for those that are interested. So far everything has been ok!
