Guys, tell me, are we so unlucky or after servicing the servers, the kinahs from the box in the udas became 2 times less? Last week, only once was the amount 1.1 + kk, mostly 2 + kk.

This week, leaving almost all attempts, only 1 time was more than 1k, mostly 900k.

Is this a hidden weakening of prey or is it all the same bad luck ?!
