Infuriating LP Gain/Loss bug

Hi,

I've won 17 lost 3 in my last 20 and get 16 lp per win and lose 26 lp per loss even on win-streaks and with a 62% winrate. I think my hidden mmr is still correct because I skipped a division on promos, but man I can't help but be annoyed with being treated like I am on a massive loss streak when I am actually on a winstreak.

Please address this
