Level 2962 error – Bubble Witch 3 Saga Review

I am on level 2962 and about halfway through popping the bubbles all the bubbles disappear except for the ones that I can shoot. It allows me to continue to shoot the bubbles I have left but I cannot see anything on the screen. When I run out of bubbles the game does not reset for me to try again. I have to restart my iPad and open the game again and I can redo level 2962 but the same thing happens again.
