Hello Aternos Team!
It would be nice if you could add this mod for 1.12.2:
Mod Name: CraftableMobs
Mod Version: 1.12.2
Mod Link: https://minecraft.curseforge.com/projects/craftablemobs
Mod Description: CraftableMobs is a mod that adds crafting recipes for spawn eggs and spawners, and allows to change the mobs spawned by clicking the spawner with a spawn egg. It's a simple addition that can be used to make vanilla-like farms of different types of mobs.
Thanks!
