Defeated mushrooms did not count in the challenge. I need one more mushroom to reach the goal, however, I collect 3 defeated mushrooms when I start the game, these 3 didn’t count in the challenge.
They were asking for expeditions? For expedition you have to pick fruits and/or seedlings, the mushrooms doesnt count as that.
For a try in you dont have expeditions, without walking, use the daily detector (it’s the first icon in the map); it give at least a seedling and a fruit to me, usually more.
