Warning on server startup due to missing reference map

Mod Loader

NeoForge

Describe the Issue

A warning appears on server startup due to being unable to read inventoryessentials.refmap.json. This appears to have no impact on function, but it would be nice if it were resolved to reduce unnecessary noise in server logs. Thanks for the mod!

[main/WARN] [mixin/]: Reference map 'inventoryessentials.refmap.json' for inventoryessentials.mixins.json could not be read. If this is a development environment you can ignore this message

Expected Behavior
No warnings in logs on non-development environment.

This is fixed in future releases of Minecraft 26.1 since refmaps have become obsolete there.

It is not trivial to fix in earlier versions because the file is used across multiple loaders that all handled mappings and refmaps differently.

You can use one of the various log filter mods or a custom logger configuration if you absolutely need to get rid of it, but the message is completely harmless.
