Hello,
actually I try to figure out, how I can deny the spawn of Zombie childs or only allow Zombie adults.
Couldn't get it to work with the wiki.
Maybe someone can tell me here, what I need to write into the spawn file. 🙂

This can just be done with the forge config. In forge-server.toml in your \world\serverconfig folder set
zombieBabyChance = 0.00
