Hello.
I come across a fairly well-known concern that wyvern fire, ice, lightning, poison & griffins spawn in numbers. It is unlivable. I obviously tested all the commands and topics found on my problem, without success, after a kill of the wild mobs, the griffons and wyverns are again outnumbered after a few minutes ...

I am at the end of the line and I have no idea.
If a charitable soul could help me ...
Thanks; w;
