[CLIENT/BACKEND] You don't always get a free win when you've previously been in series for that tier
I was silver 2, 100 LP on the way to silver 1 earlier this year in June/July? I don't recall if I made it into silver 1 or not. I'm currently Silver 2, 100LP again and I did not get a free win. I slid down to Silver 4 (I think) between then and now, so the back end doesn't quite understand that I've been here before and isn't giving me the free win. I suspect this may have something to do with how far I've fallen and the rise back up again. I'm sure the data from op.gg isn't the best source of truth, but it's close enough that you can see the dates to do your own investigation.
