as the title says
the setup are some simple mods like S+, Awesome Spyglass and ofc a stack mod
i removed the stackmod and created a new world: got nice ammount of dinos spawning. didnt check genesis creatures yet
afterwards i tested other stackmods and all i tested failed except HazeStacks: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1645346094
but even with HazeStacks there are very low spawns and mostly Thorn Drakes ?!
