New Champ Select Bug

So I was just looking at a bronze player's profile after a pretty cringeworthy performance by them in a ranked match and I was kinda laughing that they only have 5 mastery pages and 1 of them doesn't even use a keystone.

About 15 minutes later I queue up again (I never closed to client since looking at their profile) and I notice all my mastery pages are gone and replaced with the 5 scrubtastic pages I was just laughing at.

Clearly this new champ select system was never ready for public release after looking at all the OTHER known problems that are still ruining champ select.

TL;DR If you view someone else's profile/mastery pages before you queue up in ranked, all your mastery pages will be replaced by theirs in champ select (pretty f---ing game breaking honestly).
