When I was playing as Wormwood I noticed that I was able to plant seeds and pine cones on runic turf without using a pitchfork but not on rocky turf, and runic turf appears to be another version of rocky turf.
I didn't try to plant Lureplants on the turf yet but perhaps they need to be updated too?
Steps to Reproduce
Play as Wormwood and plant some seeds on runic turf.
This issue has not been confirmed by a developer yet.
