I'm sure it's somewhere in news posts that I could probably find if I tried real hard, but I'm not certain enough to dig far enough: why do some of the minions in the "minion zoo" section of collections say they have no stats and only have the option to remove?

iirc at one point in time there was gonna be a minion battle type of thing(think similar-ish to the coliseum) but got abandoned so those might be from that time frame, might have been different, but do know at one point we were supposed to be able to train certain stats

the battle function is still active/accessible if you click the image of any minion that does have stats
