Dis I asked the same thing, but I remembered the temporary added bucket if you’re hitting someone. All I did was check if they were in my range and it popped up
This has to do with hitting someone active, during this time you can hit 2buckets up/down from your bucket range. If you don’t know your bucket number please use the calculator on this thread to find out what your number is and also to get a better understating of this temporary bonuses.
