Today I was farming, and when my plant fully grew up I clicked inspect/guide and it picked the herbs for me.
(The actions inspect/guide also picks up the plant when its grown up)


EDIT:
Also when I click on a seed and then on a patch, it plants the seed in the nearby patch and not the one I chose.. and then I click again to plant on the patch I chose and it says 'You already have something planted in this patch'
when its showing that the first seeds was planted in the nearby patch, but after a few tries, I can plant in the first chosen patch.
