So i have Minecraft fabric 1.21.8 and im using the essential mod and i basically “cracked” th mod by using another mod called prometheus but when i play with a friend on a lan server he cant see all the stuff that were previously non free and can only see

When using mods like Essential in Minecraft, especially in a multiplayer setting, it is important to understand how permissions and features are managed, particularly when using tools like Prometheus to modify the mod. Here’s a breakdown of potential issues and solutions:

**Mod Compatibility**: Make sure that both you and your friend are using the same versions of the Essential mod and Prometheus. Any mismatch can lead to different experiences in gameplay, including visible items and features.

**Server Settings**: When using mods in a LAN setting, the server (in this case, the game hosting the LAN session) determines what features are available to all players. If your friend is not seeing the additional features or items, it may be that the server is not allowing those modifications to be shared properly. 

**Mod Licensing**: Keep in mind that using a mod in a way that 'cracks' or bypasses normal licensing restrictions may violate the Terms of Service of the mod. It might be wise to review the mod's terms to understand the consequences of using it in this way.

**Configuration Files**: Check if the Essential mod or Prometheus has any configuration files that dictate what items and features are visible on the server or to other players. Adjusting these settings might help in making the extended features visible.

**Use of Mods on LAN**: Sometimes, in community or modded servers, specific features are restricted to the client that owns the mod or those who are properly authenticated. If your friend does not have the same setup or permissions, they may not see the same content.

**Alternative Client**: If the issue persists, consider using an officially supported version of the mod without the cracked features for both players. This may help maintain consistency and functionality when playing together.

**Documentation and Support**: Refer to any documentation provided with the Essential mod and Prometheus. Forums or community discussions might also be an avenue to find others who have encountered similar issues and can offer solutions.

If you'd like to continue using modified versions of mods, consider engaging with creators and communities that focus on modding to explore legitimate and supported ways to achieve your desired outcomes.
