Love the game, first off.
Not much of forum poster in general but have had issues with some achievements ( I believe just from Primal Calling DLC) and some general weirdness.
Issues - The Druid and Barbarian creation achivements have not popped for me despite creating a number and playing a number of hours with couple versions of each. I have also finished the Wanderer Background Quest a couple times with "On the Road Again" popping. I am unware if any hidden achievements are link to that DLC.
Weirdness - All the hidden achievements (including some refering to stuff I had no idea about even after multiple completions) showed up briefly, a few days ago, during one instance of me looking at that page and then were hidden again the next time I looked. Not a huge deal but I though someone might want to know.
Any similar issues for others?
