Will those special guests visit again?

I botched it up. While submitting the potions i thought why not complete my market demands first and then give the potion to Diona. Apparantly, when you end the cycle it automatically means they don't get any potion. And I didn't know that. After looking up it seems they give you huge rewards which I missed. I still have 4 cycles left though. Will they come back again or did I just lose a lot of revenue for nothing?
