I've completed the level again and it is cascading a second time with no end in sight. Major glitch. Please let me know when you fix it. As it is, you can't pass level 2615.
I also completed level 2615 today and it is still cascading. At least put a stop on how long it can cascade. Let me know when you fix the bug so I can try the level again. Been cascading for over 2 hours still going on.
