How to Host a Little Bit Large Server (NeoForge 1.21.1 Setup Guide)
Little Bit Large is a NeoForge 1.21.1 modpack built entirely around size manipulation — shrink to insect-scale, grow to giant-scale, and watch the world change meaningfully at each tier. It's a genuinely unique catalog slot: no other modpack centers size as the core mechanic, so hosting it well means giving the server enough headroom for size-tier world changes instead of treating it like a generic tech or magic pack. Here's how to get a Little Bit Large server running cleanly from the first boot.
Start with at least 6 GB of RAM allocated to the server. That's the recommended floor for Little Bit Large's own modpack listing, and it covers the extra chunk and entity recalculation that happens every time players shift between insect-scale and giant-scale.
Import the modpack through CoalHost's one-click Little Bit Large installer rather than copying files from a client export — it pulls the exact NeoForge 1.21.1 version and mod list the pack expects, so size-tier logic doesn't desync from mismatched mod versions.
Watch the server log through the full first boot. Let NeoForge finish loading every size-tier mod and world-generation hook before calling it ready — a server that looks 'done' halfway through loading can misfire size transitions once players join.
Only invite players once you've seen one full clean startup with no errors. Little Bit Large's size abilities hook deeply into world and entity systems, so a server that hasn't finished initializing cleanly is far more likely to glitch a shrink or grow transition mid-game.
Back up the world before any loader update, config change, or size-tier content update. Losing a world here doesn't just cost blocks — it costs every size tier a player has unlocked and the progress tied to using size-specific abilities to solve challenges.
Use a cleaner Little Bit Large path
CoalHost is built around modpack hosting, which makes Little Bit Large much less annoying to launch correctly.
