Open Almost no mob spawn

Summary of the problem Almost no mob spawn

Pack Version 1.2.1

What is the bug? In my world are sheeps, cows like normal but
almost no zombies, creepers etc.
In one night I only found 3 mobs.
I get more skeletons from the skeleton-invasion than from natural spawning!
It's since the beginning (24 ingame days).

Mod & Version
Just normal

Make sure your render distance is set to 10 or higher. This is a vanilla bug that you are experiencing.
