Demoted from Diamond IV to Plat 1 (it has only been 17 days)
UPDATE
UPDATE: As of 9:21 PM PST, I just finished playing a normal game, and then it brought me to a screen and said I got promoted to Diamond IV. So it's fixed now YAY! Hopefully you guys get the same treatment too.
UPDATE2: I'm back to Diamond IV, so I played a ranked game. I won and got 13 LP. However, while my profile still says I'm in Diamond IV, when I go to the "ranked" tab, it shows I'm Plat IV 13LP, when it's supposed to be Diamond IV 13LP. So it's still glitched.
I hit diamond IV on March 18th. Today is April 3rd. It's been 16 days. This morning I logged in and it said I was demoted to Plat I. I was very surprised because 1) it has not yet been 28 days 2) it did not warn me like it used to that I need to play a game or my LP will decay.
Please look into this because it seems I'm not the only person experiencing this it seems. I submitted a ticket already; I will not play ranked at this time as I am going to assume it's a bug via the new patch. Will wait to see what a Riot person will say. I poured countless hours into ranked play to hit Diamond IV; this is very upsetting. Please explain when this will be fixed, thank you.
Taken directly from ranked play FAQ, "DECAY Diamond, Master, Grandmaster, and Challenger are all subject to decay. In Diamond,** after 28 days of inactivity in any ranked queue**, you'll begin losing LP based on your current tier. Every seven days after that, you'll lose LP until you play a match in that queue. Diamond players lose 50 LP each time they decay"
