"The ⭐8 quests A Portent of Disaster and A Blaze on the Sand require 10 and 15 fully researched monsters to unlock, and are required to complete." This is not true. I'm on PC and have not unlocked these quests. I have completed all other quests from 1 star to seven star and all 8 star quests apart from the two stated above and the other two stated in the requirement description and i have unlocked the white winds of the new world. though i have not been able to unlock the rainbow pigmnet, to my knowledge.
