How to Fix a Cursed Walking Server That Keeps Crashing
Cursed Walking's own documentation is specific about what breaks it: OptiFine needs four other mods removed to coexist, version mismatches between client and server are unusually strict (down to the Forge branch), and 225+ mods want real RAM.
See the Cursed Walking pack page for sizing before you chase anything else.
1. OptiFine without removing its four conflicting mods
OptiFine isn't just "not recommended" on this pack — it specifically conflicts with Oculus, Rubidium, Entity Texture Features and Entity Model Features, and all four need removing before OptiFine can run safely. Given the overlap in what these mods do, most players are better off without OptiFine here at all.
2. Client, Minecraft version, and Forge branch all need to match
Cursed Walking is strict about this three-way match: every connecting player needs the same pack version, the same Minecraft version, and the same Forge branch as the server. A mismatch on any single one throws a crash that reads like a mod conflict but is really a version problem.
3. Manual mod uploads instead of the official server files
Building the server mod list by hand from the client pack — rather than installing the pack's official server files — is a documented cause of crashes here, since client packs include files that were never meant to run on a dedicated server.
4. RAM for 225+ mods
The pack's own guidance is at least 8 GB given its size. Below that, expect the usual cascading pattern — GC pauses, then a tick timeout, then a full crash — rather than a clean error pointing at one mod.
FAQ
Can I use OptiFine with Cursed Walking?+
Not safely without removing four other mods first: Oculus, Rubidium, Entity Texture Features and Entity Model Features all conflict with OptiFine on this pack and need to go if you want OptiFine running. Most players are better off skipping OptiFine entirely.
Why does my friend crash on connect even though the server is up?+
Every player needs to match the exact Cursed Walking version, the same Minecraft version, AND the same Forge branch as the server — a mismatch on any one of these three throws a connection crash that looks like something else.
I manually copied mods instead of using the official server files — is that the problem?+
Likely yes. Client packs bundle files that don't belong on a dedicated server, and manual uploads skip whatever filtering the official server-files release already did. Reinstall from the official Cursed Walking server files rather than hand-assembling the mod list.
Host Cursed Walking from the official server files, sized right
CoalHost installs Cursed Walking from the pack's own server release at 8 GB+, with client-only mods already filtered out.
