Design challenge unplayable on 10th generation iPad.

There have been a lot of posts about the game freezing when you try to move buildings or fix roads, etc. Today I’m trying to play the design challenge and it has become completely unplayable because it freezes up and does that weird purple and black pixel thing every time I try to do anything! I can’t change a road, I can’t place a building, I can’t put a tree anywhere, nothing. I’ve deleted the game and reinstalled it twice, and I still can’t do anything in design challenge. The game is working pretty well and only freezes occasionally in my capital city and the other regions but today for some reason, the design challenge just went haywire. My City is 3/4 done for the challenge and now I can’t finish it to submit it. Anyone else having the same issue? Today is Saturday, November 8, 2025.
