same question here. I just saw it. Do i need to use this somehow under "map" in the server settings?

I found it, the dev mentioned it in another post.
Its found here:

(Its on of the 20 pictures he provided, i personally would never have found it there, since i checked the whole mod description and the pictures seemed to only show the newly added looks)

so we need to put this more top than bottom.
i clearly saw some clown from this mod in some maps. i guess its just "special spawn" and not random spawn?

can we change this order safe mid game in a server? :o

I was not able to get this to work. At least did as in the picture, even checked via debug.
But was not able to finde even one special zombie..

try to spawn in big city like louisville.

i confirm that i got azspawn at the bottom and i got a special clown from the mod. maybe i will not get "special spawn" from the mod but only random encounter i dont know how its working. but you dont have authentic Z zombies all the time too! you may encouter biggy zombie and dont even knoow its modded. this mod is awesome for that :)
