Darya's ability to ignore prey rules doesn't work on the cowgirl's two capacity rule after three have already been eaten. Also, her ability nullifies taking no space, but doesn't stop from eating those prey when full (which that one is fine. I don't mind getting to cheat like that lol)
Figured out that what's actually going on is that the pred's abilities just don't apply before being fed. I get the feeling this would be too much of a pain to fix as the means by which information is communicated between pred and prey would end up getting more complicated. So it might be better to just have this be an official rule to the game?
