Pro League: Icicle cup
End date: 8th Jan 2019
I scored 1827, rank45.
Originaly, that would give me 3.000 crystals and 3 pro chests.
Since nobody got the top rewards, all tier rewards were adjusted, so my score bumped me up to 8.000 crystals and 5 pro chests.
However, I still only got the original 3000 crystals and 3 pro chests.
I confirmed in game that indeed I only got 3 pro chests and my crystals only went up by 3.000.
This happened to several alliance members as well.
