Charm Interrupts Cannels

Heyy~

I'm an main and I would like to point something out with the latest patch (7.12).

Previously while 's R - Glacial Storm was active, and charms would not interrupt the ability. Currently, that's exactly whats happening. I noticed that this patch had a bug fix for "charmed targets no longer walk in the wrong direction," and was curious if this bugfix was the cause. It could also be an undocumented change, but regardless would like some insight on the situation.

Also would like to note on the LoL wiki, it says charm interrupts all forms of channels except Glacial Storm, just to confirm that charm, in fact never interrupted the ability.

Thanks~ -Glacial
