What you were expecting to happen, and what actually happened:
When an Archdruid spawns a Dryad on death, there shouldn’t be a Forest Herb icon underneath the Dryad because the Dryad does not use green mana. However, one does appear.
I do not believe that this actually causes an extra Forest Herb to be awarded in addition to the one that is (correctly) dropped by the Archdruid, so it appears to be only a visual bug.
How often does this happen? When did it begin happening?
Every single time that an Archdruid’s Nature Pact trait procs since the Legends Born event started.
Steps to make it happen again
Explore in Forest of Thorns until a Dryad is spawned when an Archdruid is defeated.
