Ive got manas semi balenced plus I enjoy them, I see about 8-10 throughout my entire snow, they just engage everything so they definitely get annoying at times.
And I found with admin cmnds how to spawn a drake nest but they dont stay lol unrender when you leave.
I'll have to add the manas again. Just bump the numbers down. I had like 50 of them. It was chaos. I have dinos dropping fert drake eggs but they come in no health so they're use less lol
