Right thanks! By default army ants are designed to pick up food, but obviously in the formicarium spawner they should not be! Will get this fixed today.I've been in my formicarium using the creature spawner although 1 army ant decided to grab the corpse of a spiny devil cricket this happened similar to 3.2.
And see those numbers? Those are food values but there is no food, it shows on the map but there is no food...
