If I remember that's not a bug, you can buy an infinite amount of generator but there is only 20 rank (so the production triple only 19 times and you earn generator cards also 19 times).

soon enough e30 will come out and it's got some CRAZY objectives (all in #💬-beta-chat )
rank 20 is 1500
after r20 buy rank is buy 200
