Unlucky or?? 17x audience run - 0 ingenuities

So I was farming quite a lot of invitation. Usually every 2-4, sometimes even 5 runs i got at least 1 ingenuity. This night I was very bored and just bought 17 audiences for ~~ 100 div, was wondering if I will lose or gain. Well, i lost like 98 div.

So, the question is - did I just get super unlucky or ingenuity drop rate changed overnight lol
