I think I'm the extremely unlucky one. I play the game every day and it has been at least 2 months since I got the sister and persuasion quests. I only got ONE inscription!!!!!! And that's the very first one we get when receiving the quests!!!! I'm sooooooo mad and have huge problem in getting trap plants. This will take me forever maybe 10 years to get 20 inscription in this speed. Ridiculous!
