Bug With Autofill
I can only assume this is a bug now, though I posted another post in gameplay before I assumed it was.
To summarize, the day the new patch dropped I was getting awkward issues of two autofill games in a row (autofill activated over protected even queuing up as support) then 1 of protected, instead of the normal reverse.
Today I had 4 games in a row of autofill. I had queue'd up as support preferred each one (is what I do when autofilled so I don't get jungle). First game someone was kind and switched me I believe it was top. Then 2 more after that as support. I then got into a series and instead of the protection you are supposed to get with a series, once again autofill was activated.
Reset the client twice and it was fine. Next game same again, reset the client once and it was fine.
