I guess I found a bug in ladder.
This is the screen showing ladder after RoC -

And now, this is the screen which I took today -

Looks strange, eh? NOEH didn't lose any LPs and gained 3 positions as a result.
By looking at the ladder, I can say that players from outside the europe (NOEH is from Brazil) didn't lose any LP at all - at the moment there are 111 players who are over 90k - 100 from europe (as it should be) and 11 from other continents. I think it should be taken as a whole, 100 players over 90k, no matter where they are from.
I hope it's just a bug and it will be fixed.
If this is how the new continental ladder works, I'm really disappointed. Many players from europe can now change their location to other continents and play for ladder without a loss of LP.
It’s important case and I hope someone from NADEO will give an explanation about it.
Thanks!
