Need to remove Pellucid Grotto from the zone list for Koraskian Sprigget. It is not foraged in Pellucid or any other Underfoot zone. It is only foraged in Rathe Council Chambers (Seeds of Destruction).
I spent well over an hour with my Druid trying to forage these in PG and got none. I went to Rathe Council Chamber and got one on the first and second attempt.
