I just downloaded your mod for the first time (so I got the latest one), and there are a few things that immediately stand out to me by looking at the skills menu.
...Is this intentional? Are there really only two and three levels of the new perks respectively? It won't let me unlock the last few levels, despite having Fortitude and Intellect maxed out.
Also, seed packs have no info on how to unlock them. The XML file says they're unlocked by the Planting and Growing perk, so I assume you have to have that maxed out to unlock the seed packs, which it's not letting me do.
