Hey Nekres,
I’m currently rank Platinum III but your API shows that i’m Plat IV. There has never been a rank “platinum IV” in the game so you might wanna update it as soon as you have time for it. 
Points are correct though!
I haven’t tested other ranks, I just know that there is this problem with platinum ranks…
This is the pic with the ranks if it helps you find it faster
Thanks in advance!
