Great but crashes – 4 Pics: Find the odd word II Review

Good brain teasers. It worked great up to a point, but there must be a bug. At level 5, with 19/20 complete, app crashes every time. I uninstalled, reinstalled, worked my way back to that point and it crashes when I select "level 5" off the choose level menu. iPhone 5S, ios 7.1.1, gigs of free space.
