We detected an error in **stderr_stream.log** about duplicated packages:
**Modules luna_minecraft and e4mc export package link.e4mc.neoforge to module diagonalfences**
This error means mods are exporting packages with the same name to the game, while only one can be loaded.
**Basically, this either means the same mod is present twice, or there is a dependency conflict.**
You have 2 ways to fix this crash:
1) **[RECOMMENDED SOLUTION]** Keep **only one** of the mods listed below,
and report the issue to both mod authors. They should relocate it or use jarInJar for their dependencies.
2) **[TEMPORARY FIX]** This is not recommended: it sometimes works, sometimes doesn't, and can cause unexpected issues.
Open the mod as an archive and delete the '**link.e4mc.neoforge**' folder in all mods listed below except one.
Mods containing the mentioned package:
luna_minecraft-neoforge-5.3.1.jar
