I can't agree with that. You understand that this is not a regular Wikipedia, and access to editing and creating articles in it is only available to DM himself and mb someone responsible for it (from his team). So this is not a case where some incompetent person from the internet corrected something in "usual" Wikipedia and now this information cannot be trusted.
By the way, the article about the Farm was created on June 26, 2020, i.e. at that time, Ep2 v13 had already been released...
Moreover, what we know about this Farm in the game does not contradict what is written in this article. It's just that the article presents all this information in a more structured and complete way. Therefore, for me, it is definitely canon. As for the Ep1, DM once wrote that he didn't initially plan to make the game beyond Ep1. So, i suppose, If he hadn't succeeded with FB, we not have seen even Ep2, heh.
