[Investigating] Lightning Bolt not proccing

Platform, device version and operating system
I play on PC, Android and Xbox, but I suspect it’s across all platforms

What you were expecting to happen, and what actually happened
Lightning bolt states that it has a 30% chance to destroy 3 columns when cast. I noticed it never seemed to be destroying the 3 columns when cast, so I started recording how many times I cast Lightning Bolt and last night I cast it 24 times in a row and never once saw the 3 columns destroyed. I ran this through a probability calculator and the odds of this are: Probability of B occuring 24 time(s) = 0.724 = 0.00019158123138057(Probability B is 70% chance that the event doesn’t occur)

How often does this happen? When did it begin happening?
Seems to always happen for me on my Shaman who has this spell equipped.

Steps to make it happen again
Cast Lightning bolt and see if we can get the 3 columns to get destroyed.

I used it in the previous yellow tourneys and it was triggering quite frequently for me.
If there is a bug it may be related to specific pairing of items, so maybe you should provide information about your loadout.
