Something is wrong. I'm in level 19, so I already know that sometimes you got trolled by losing to a weak team. But in the actual season it happened so many times. Like 4 times in a a row. I have one 7 stars player, four 6 stars players and the rest is about to get the sixisest star. I caught myself losing to average teams (a lot of 4 stars players, sometimes even 3 stars)... Ridiculous.
My team always rest and with full moral.

Ah! I forgot to mention... My last two results were 0x4... Against worst teams...
