Minecraft Versión: 1.16.5

Forge Versión: 1.16.5-forge-36.2.2

Mod Versión: BetterMineshafts-Forge-1.16.4-2.0.4

Mods I have installed:

1. BetterMineshafts-Forge-1.16.4-2.0.4
2. YungsApi-1.16.4-Forge-12

My problem is that by creating a new world, Mineshaft doesn't spawn.
I try to search with the /locate command but when I use the command I get the following message ''Could not find that structure nearby'' It don't matter if I walk a thousand blocks they never spawn.

The command is /locate bettermineshafts:mineshaft. Try that and see if it works
