I am currently a little more than half way thru level 16 and expanding the town, adding buildings, etc. Just finish the nuclear plant (did not have room before). 2 days ago I clicked on something (don't remember now) and the screen went black. I have tried signing off--can't get signed back on, looked at the app store to see if it needed an update (didn't) and even signed off icloud and back on thinking that would help. Nothing has and I am at a dead end. Has anyone else experienced this and what do I do now??? Oh, btw, I play this on my ipad---would that make a difference??
