I dont think putting the Dinos in the tropics was a good idea. First off there is the fact the bigger Dinos are breaking the terrain and making it glitch and you loss the ability to fall were some of the blocks were.. Second, there is the fact that the more Dinos that spawn in an area the less of anything that is not a Dino can spawn. This gives you a smaller chance to find that last iguana needed to get your scale armor set finished. Although i do like that i got the Dino meat to start my Dino museum and zoo.
