How to Host an Immersed With Nature Server (NeoForge 1.21.1)

Start from at least 6 GB of RAM — that's Immersed With Nature's own recommended floor. NeoForge plus Alex's Mobs, Serene Seasons, and Farmer's Delight running together need real headroom beyond a vanilla server, even though nothing in this pack is doing the heavy chunk-generation work of a combat-focused modpack.

Import the modpack from its official NeoForge 1.21.1 release instead of rebuilding it from a client export — mismatched versions between Alex's Mobs, Serene Seasons, and Farmer's Delight are the most common cause of a server that boots fine but desyncs seasons or mob spawns from what players actually see on their client.

Watch the log through a full first boot and confirm Serene Seasons initializes its season cycle and Alex's Mobs finishes registering its spawn tables without errors. This pack leans on slow, ambient systems, so a quiet mod failure is easy to miss until a season transition or spawn event breaks later on.

Only invite players in once that first boot has completed cleanly end to end. Immersed With Nature is built around noticing gradual environmental change, so a world that started on a broken mod load will feel subtly wrong — missing wildlife, a season that never changes — in ways that are hard to diagnose once people have already settled in.

Take a backup before importing an existing world, updating NeoForge, or changing Serene Seasons' season-length configs. A season cycle or an Alex's Mobs population that's taken weeks of real time to build up is exactly the kind of slow progress this pack is about, and it's not worth risking on an update.
