Just habit for me. I always work on the daily goal and just drop the chests on my board then chop all three at once. Sometimes I forget to chop the chest and they stay in storage or on my board until I remember then pull them all out at once out of storage and chop them all.
I just hate not knowing if I could have cleared the Fungi Five with that one lost midnight mushroom today. Sigh. I hope Enoki wasn't in that mushroom.
