Herbalist Tomira's quest won't trigger: why?

[The A.W.G.]

Long story short, this is my second time trying to play the game, first time I quit because I discovered you can fail quests and I didn't like it. The quest I failed was the one given by the cute herbalist, Tomira. So this time I wanted to do things right and after I talked to the Nilfgaardian guard I immediately headed for her house, ready to make her happy...
...only to discover her quest didn't trigger.
I just completed all the available missions and locations in White Orchard (only thing to do is leave with Vesemir) and Tomira was nowhere to be seen. Do you have any idea what the heck could have happened?

With Tomira I have no idea I had the same with Hunter, I found Griffin trails before taking quest and I had to reload previous save (like lost 2h of exploring :D ) but it triggered after all. For Tomira thought I didnt had problem even thought I was gathering herbs like crazy. Maybe try also reload some previous save file?

Did you do any exploring and find the herb on your own? That kind of messes things up, just like finding the trail to the dead griffin messes up being able to speak with the hunter.

Yeah, I'm quite sure I got the herb before. So there is no way I can meet the cute herbalist?! I'm devastated.
Don't get me wrong, I'm loving the game, but its quest design seems really... wrong.

EDIT. So I went to Tomira's anyway and I found her, I talked to her and the mission to "save" her friend still was availabel, even if there was absolutely no mark on the map. This is good so I can finally do that quest but... I could have easily skipped it if I hadn't already knew about that. I wonder how many such cases are in the whole game...
