So me and my friend were doing stuff in bloodtide coast, untill we go to this one heart. “Help Cesselia defend and research the oasis” In this heart you have to pick up a bunch of stuff from around the place, and talk to Cesselia to mix the potion. But what we noticed is, that while “Triple Trouble” event is going on, she is unable to mix potions. When you talk to her during the event, nothing happens. There is no option to mix potion. But once “Triple Trouble” was over, we could finish that without any problems.
