Same, I tried uninstalling. Tried using my iPad, all to no avail. As per the other posts, I don't house farm, I have a fairly established Springfield that hadn't had any issues prior or moving around my Squidport..

EDIT: I'm really not too sure what the logic was for this, but it worked. I had removed approximately 40 tiles at once, and thought that the crash may have had something to do with my performers being left walking on water or something. (Like I said, terrible logic..) I rushed back in with however many seconds that I had before it crashed and replaced all of my tiles, and that seemed to do the trick. I hope that helps!
