Check your journal. Do you have “A Demanding Chef II” or “Forest Secrets” in there? Or both? This makes it easier to find out what you are missing currently.
In case you want to check what you might miss, here is an explanation of the activities of both quests:
A Demanding Chef II
To finish “A Demanding Chef II” you have to gather the red truffle in the bandit camp at the “green lady forest”. Using your pickaxe on the the red truffle in the camp. Did you remember doing that? You can not get the credit for collection the truffle as a group. You need to collect the truffle yourself. Than bring the truffle back to the chef and you should be done with that quest.
To do the “Forest Secrets” quest, you will get a pop-up of the start of the quest by walking into the “green lady forest” but only if you are on the “A Demanding Chef II” ATM. From there you have to find an item on the table of the same bandit camp from the “A Demanding Chef II” and you have to pick it up. Then you get the message that you have to inform Bishop Roma. You can find him (and the guard you actually have to talk to first) in Highsteppe. But only after you collected the item from the table in the bandit camp.
