problem with Yew Leaf

[Artemisia]

3 hrs in WL with max forage and machete, 0 leaves
found about 10 groundspawned ones but for some reason I cannot pick them up, the green diamond is on the floor but no pickup


anyone else have this problem?

edit: make that 4 hrs

edit : days later, various reboots, advanced patches etc and I still cannot pickup groundspawns.
