I just downloaded the mod and I want the eggs to spawn in mineshafts, but I cannot for the life of me find the right file. Yes, I know it's supposed to be in the world folder. Yes, I checked, it's not in serverconfig. I've never downloaded a mod until now and I'm extremely confused and frustrated. The only file that's in serverconfig is forge-server, which has true/false stuff in it, but none is what was listed on the instructions in the configuration wiki on this site. Please help, I'm so lost.

Look for the serverconfig folder on a created world, option is in there

I did- like I said before, the only file in that folder is forge-server, that file just doesn't exist for some reason.

I cannot reproduce this issue.

Please ensure you have everything installed correctly.
