I'm having some trouble with the flowering spriggan quest. I picked up a spriggan host body during the Nettlebane quest and attached it, then went around and got commented at by NPCs, and asked several. I eventually talked to Farengar and he mentioned the temple of kynareth, so I went there and got the book, and now it's pointing me to "the grove near [...]" with no marker or anything. And the very first goal of the quest isn't marked as completed as well, though the other two goals (not the "find grove") are.   From what I read, I think I skipped an objective gotten from people mentioning something about "magic" and that might have messed it up? But I admit I don't know anything about how quests progress.
