As a stress level 108 referral, I should’ve got 360x update cards and my recruit should get 90x update cards. But I got the same amount of cards as my recruit i.e both got 90x cards.
That’s the bug. I, the referral can’t seem to get the exact amount of update cards as promised. I faced this bug on both lower & higher milestones; making a total of 6 times.
But note that I do get every other rewards such as coffees, tears normally without facing that weird bug. Maybe because we both get the same amount of them? Could be.
From below screenshots you can see that I, referral “OMAR676” got the same amount of cards as my recruit “ydosyslvsl5w” where I should’ve gotten 360x instead of 90x cards.
.
I didn’t paid much attention to this bug at lower milestone as the rewards were low but with increased deficulty, the rewards did got better by a large margin to the point I just can’t turn a blind eye anymore.
Not to mention update cards are really SCARED on high stress levels such as mine so I’m really in dire need of these 
It’s funny that sometimes ago I didn’t like having update cards on lower stress level.
Anyway, I hope the devs fix these bugs as this whole recruiter/recruit system is very great and makes a whole lot easier for veterans & especially newbies to get progress & ultimately fun! Not the mention the rewards gets only better to ultimate!
