LP / Elo visible Bug

Hi all,

I know loosing games is something normal, but it should be consisdent, even therefore I need to report 2 Bugs:

1.) I logged out on saturday with around 36 LP, ok but to be true, I was a not on my best mind on saturday, and I thought hey alright I lost em again, who cares dont worry sunday morning thoughts. After getting a good moment in my life again, i recognized I quit the game with 2 wins on this saturday, but i had -8 LP on sunday, this was odd to me, but to be fair as I thought ok you lost it. (me)

Then this happend today to me today:

2.) After getting a little progress after my promotion games i feld really confident.

This day I played up to 40 LP Points. After the next defeat, I loose a game and get -20 which is okay for me!

40-20=20

But the thing is I am now after this loose in a position where I have 0 LP. This seemes pretty special to me.

Ok no one likes math, but there is something wrong! Investigate it.
