How to Fix a Prominence II: Hasturian Era Server That Keeps Crashing
Prominence II: Hasturian Era publishes its own troubleshooting page, and it puts RAM and shaders ahead of any specific mod — worth following in that order before chasing a crash log line by line.
See the Prominence II pack page for sizing before you chase anything else.
1. RAM below 8 GB
The Prominence II team's own number: 8 GB for 3-4 players, roughly +1 GB per additional player. Paying/public servers commonly run at 8-10 GB. This is the first line of their own troubleshooting checklist, not a generic recommendation.
Below that floor, expect the cascading pattern — GC pauses that feel like lag, then a tick timeout, then a full crash — rather than one clean error pointing at a single mod.
2. Shaders and extra client-side mods on the server copy
Second on the official checklist: remove shaders and any extra mods from the server install specifically. Shader packs have no function on a headless server and some combinations are known to cause startup instability.
3. A known, fixed chunk-corruption bug
A specific bug existed where walking into a chunk containing a glitched structure could crash the server, chunk-ban the player who triggered it, or roll back recent progress. This has been patched upstream — if you're hitting exactly this pattern, check that you're on a current pack version before assuming it's something else.
4. When to just reinstall clean
The pack's own guidance treats a clean reinstall as a legitimate troubleshooting step, not a last resort — after confirming RAM and removing shaders, a fresh install from the official server files rules out a corrupted or partially-updated install faster than debugging configs one at a time.
FAQ
How much RAM does Prominence II actually need?+
The pack's own team recommends 8 GB for 3-4 players plus roughly 1 GB per additional player. Paying/public groups commonly run it at 8-10 GB. Below that range, instability shows up as GC pauses and lag before an outright crash.
What does Prominence II's own troubleshooting page say to check first?+
Their quick checklist is: confirm 8-10 GB RAM is actually allocated, remove shaders and any extra client-side mods from the server copy, then reinstall cleanly if problems persist — in that order, before chasing a specific mod.
Can a crash permanently break a chunk in Prominence II?+
There was a known bug where entering a chunk containing a glitched structure could crash or even chunk-ban a player, or roll back the server. It's since been fixed upstream — if you're still hitting it, you're likely on an older pack version.
Host Prominence II at the RAM the pack's own team recommends
CoalHost sizes Prominence II at 8 GB+ from the first boot, with backups in place before any risky retry.
