ummm... so about those Holstaurs... I managed to get one...
after I posted that comment, I kept playing to beat level 3 of Windhaven on Challenge difficulty. Midway through like day 7, I remembered the "specific search" feature existed and checked to see if I could get one there and well... yeah I got one for 500 gold which technically still makes them a "premium only race," but obviously this was an oversight that was not meant to be in the public version of the game.
I guess the reason I kept getting the trait was that the game lets you purchase them through this feature when you get to Windhaven 2 and thought: "oh the player is able to obtain holstaurs, lets send customers with the associated trait," even though they can't be bought through the normal shop. Funnily enough, getting her didn't unlock the race's animations in the gallery. I know this was unintended and probably happened because nobody else knew this was even a feature so it got unnoticed for months, so I thought I should let you know.
