When picking turmeric I got this message:
[18:18:58] You aren't sure how that was growing in there.
which appears to be an indication that an unplantable herb had been planted via an exploit fixed by the most recent hotfix.
I was able to pick a turmeric but the planter transitioned to unplanted. I was able to pick the turmeric seed and replant in the same planter.
Rosemary, woad, and lovage seem not to be affected.
