[2021] I lost 1000 MMR in a win

I really have no clue what happened, I was at 2602 MMR and then I win a game and it says 1500 (+100 MMR) = 1600 MMR and I was so confused, then I checked Smite.Guru and lo and behold, I really did lose all my MMR. I love this game, I've played it since I started high school and I'm about to graduate college now. After a few losing streaks I had finally found my groove again. But nah, I lost all my MMR in a win. I don't get it.

I want to keep playing this game but I'm started to get demotivated. A post I saw recently was practically speaking how I felt about the game in recent weeks and how they found it difficult to stay motivated. If I really do have to climb back up it's going to be a massive pain and I don't know if I want to do it again. I understand if everyone resets. But to get reset to 1500 during a win streak kinda super demotivating. Anyways, here's some screenies for proof and whatnot.

If anyone can help that'd be perfect. For now I guess I could take a break, if the issue persists then I might have to consider a permanent break, this is just too annoying to deal with.
