I experienced a slight glitch with the gyrosphere gates, when I set up a small paddock with 3 Euoplocephalus and 4 Stygimoloch next to Sauropod and Hadrosaur enclosures, in which the population gauge claimed to exceed the Stygi's 14 limit, and they were able to walk straight through the Gyrosphere gate and into the hadrosaur enclosure. Fortunately, the medium sized herbivores so far seem to be unaffected by this glitch .
