Puzzle integrity disappeared.

Now that I have gotten to a higher level (more points at Hard and Expert levels) the puzzles and error checking are not functioning right. The puzzles have built-in conflicts in the permanent numbers so the puzzles are unsolvable. Below level 16 with less than 44,000 points and until Monday 11/8/16, the puzzles and logic were good. Very disappointing its no good anymore, I loved the functionality. But I need to get a different Soduko app; i will not spend time on unsolvable puzzles.
