Thank you for the clarification above!
What does "players were erroneously granted extra skill points based on the number of Champion skills they purchased" mean? Do you mean champion skills purchased from the crown store?
Sorry, no. This is referencing Champion Skills unlocked, not "purchased" in the sense of purchasing through the Crown Store.
One thing I would like to know is: Will skill point reset be on PTS for update 29 too ? I mean each time there is a PTS we have our characters coppied to PTS. 1st 2 weeks are NA characters and 2 next weeks we have EU characters.
So will we be able to test if it works (before it will go live with Update 29) ?
Yes, all skills will be reset with each character copy during PTS.
