Plenty and Pilfering scarabs not working?

Hey guys,

I've done between 5-10 maps with those scarabs x4 plenty x1 pilfering and the boss literaly dropped 0 cards.

Thats impossible unless the scarab is not working for some reason.

Could you check it please? Im sick of doing breachs 😂

Thanks a lot.

P.S

I wish u dont get me wrong way

If you need me to try something else Id gladly help.
