Mohist Mod/Plugin Conflict

On a Mohist hybrid server, a mod and a plugin both try to handle the same event and clash. Hybrids bridge Forge and Bukkit, and that bridge can break when both sides touch the same logic.

What does this error mean?
Mohist lets Forge mods and Bukkit plugins run together by translating between their APIs. When a mod and a plugin both inject into the same event, the bridge can produce conflicts or crashes, an inherent risk of hybrid servers. 
Mod and plugin inject same event
Most Common Causes
  • A mod and a plugin hooking the same event.
  • The hybrid bridge mistranslating between APIs.
  • A plugin assuming vanilla behavior a mod changed.
  • Version mismatches between Mohist, mods, and plugins.
  • An especially invasive mod or plugin.
How To Diagnose
  1. Read the crash for the event and the mod/plugin involved.
  2. Identify which pair conflicts over that event.
  3. Test with the plugin (or mod) removed.
  4. Confirm Mohist, mods, and plugins are compatible versions.
Recommended Fixes
  • Remove one of the pair
    Drop the conflicting plugin or mod, or replace it with a non-overlapping alternative.
  • Update Mohist
    Use a current Mohist build with better compatibility for your version.
  • Avoid overlapping features
    Do not run a mod and a plugin that both manage the same mechanic.
  • Consider a non-hybrid split
    If conflicts persist, separate concerns (pure Forge or pure Paper) where possible.

Frequently Asked Questions

They are useful but inherently fragile, the Forge/Bukkit bridge can break in edge cases.

The crash names the event, identify the mod and plugin that both handle it.

Where feasible, use pure Forge with mods or pure Paper with plugins to avoid bridge conflicts.
