This mod is a nice re-balance and seems to work well in my testing. However, one fairly significant issue I'm encountering is that it seems to prevent ANYTHING from spawning in the Snow Cave on The Island. I installed the mod, left settings as default, performed a dino wipe and waited a while. Dinos spawned throughout the rest of the map with the nice balance (though it does appear spawn rates are somewhat higher overall?)

However, the snow cave is completely empty. Is this a known issue?
