Modpack Version
1.5.1

Minecraft Version
1.18.2

Describe the crash or bug
From fresh serverpack install running via Windows Powershell, server generates from the same seed. Identical terrain, however random structure generation, modded and vanilla.

Steps to reproduce the behavior:
Before server start, delete "world" folder in server files, and run "start.ps1" with any seed defined in "server.properties."

Expected behavior
New generation from different seeds.

Additional Info
The generated terrain is spawn on the river shore, ocean to the north, and across river to the west is split between a forest and a cherry blossom forest.

I stumbled about this bug too.
The Problem is that Terralith doesnt use the seed provided in the server.properites. Instead it uses the seed defined in MINECRAFTFOLDER/kubejs/data/minecraft/overworld.json. Although there is a toggle to use the server.properties-Seed instead of this one, this toggle seems to only work with Forge and doesn't with fabric

Just change the seed in overworld.json and be happy :-)

Closing as 1.18.2 is sunset

Also this is fixed in 1.19.2 aqm2 you can enter seeds as normal now
