If you could let me know what issues you're experiencing, I'd be more than happy to forward over to the Dev team!
I appreciate what you are saying, Ms. Falcini.
This small update have fixed all the bugs I have once brought up. I am waiting for Steam discounts to get the Jurassic-World-exclusive species especially those in the recent Prehistoric Marine Species pack DLC.
Regarding the official Southwest USA challenge mode, I am waiting for every new DLC Frontier releases, as I need every species of prehistoric reptiles available for the Jurassic difficulty challenge.
Regarding the official challenge mode based on the film
Jurassic World in Jurassic difficulty, I am waiting for Microceratus.
The current issue I am having cannot be remedied by a small update, it is by a major update when there is a new DLC.
Which makes it so that the cohabitation preferences of various species in the game don't make any sense. They should've adopted a system like Planet Zoo where interspecies enrichment/cohabitation preferences are based on animals that a particular species would actually coexist with in the wild. For example, all the herbivores of the Hell Creek and Lance Formations should be comfortable being housed together. Same holds true for herbivores of the Morrison and related formations. The system they have now is so generic and illogical it boggles the mind. Carnivore, pterosaur, and marine creature cohabitation preferences are even more illogical when you really examine them. Point is, for your suggestions to work, the entire interspecies cohabitation system needs a complete or near-complete overhaul to reflect my statements above. Otherwise, it does not nor ever will work the way it should.
With the challenge condition of the Jurassic difficulty in the official Germany challenge mode being no more than 10 species, it is currently not playable.
Since major Update 5, there have not been any work on the dinosaur cohabitation element.
To make the official Germany challenge mode in Jurassic difficulty playable, the following amendments to the dinosaur cohabitation element are to be made:
1) Homalocephale should have similar cohabitation preferences to Dryosaurus, Struthiomimus, Archaeornithomimus, Gallimimus, and hadrosaurs.
2) All species of pachycephalosaurs, ornithomimids, and hadrosaurs mutually like each other.
3) As stegosaurs dislike ankylosaurs and ceratopsians; stegosaurs' dislike relationships should include combat-capable pachycephalosaurs such as Dracorex, Stygimoloch, Stegoceras (if added), and Pachycephalosaurus. I am willing to accept herbivores' dislike relationships based on geography and timeline.
4) All species of pachycephalosaurs and ceratopsians mutually like each other.
5) Pentaceratops can mutually cohabit with Alamosaurus; but Pentaceratops cannot cohabit with Styracosaurus, Pachyrhinosaurus, and Triceratops.
6) With the exception of Chasmosaurus, Styracosaurus cannot cohabit with Nasutoceratops and Pentaceratops.
7) Torosaurus and Triceratops can mutually cohabit.
8) Camarasaurus and Apatosaurus like each other.
9) Diplodocus can mutually cohabit with Apatosaurus, Camarasaurus, and Brachiosaurus.
