"[16:05:50 WARN]: Ignoring unknown attribute 'am2.maxManaBonus'

[16:05:50 WARN]: Ignoring unknown attribute 'am2.maxBurnoutBonus'
[16:05:50 WARN]: Ignoring unknown attribute 'am2.xpMultiplier'
[16:05:50 WARN]: Ignoring unknown attribute 'am2.burnoutReduction'

1.7.10 hasn't been supported here for 2 years. Update.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

DO NOT PM ME WITH PROBLEMS. No help will be given.

These are the forge forums, you would need to ask wherever neoforged support is given.

Hello, i'm trying to launch a server with additional mods i've added myself, and it isn't launching - but scrolling through the debug.log i came across [main/TRACE] [net.neoforged.fml.loading.moddiscovery.locators.JarInJarDependencyLocator/]: Failed to load resource META-INF/jarjar/metadata.json from MixinSquared-0.2.0-beta.6.jar, it does not contain dependency information. which came up a lot - im just wondering if this could be why my server won't launch

[main/ERROR]:Failed reading REFMAP JSON from : java.lang.NullPointerException Cannot invoke "org.spongepowered.asm.mixin.refmap.ReferenceMapper.setResourceName(String)" because "mapper" is null

this is the error message i keep getting when trying to launch minecraft from the launcher with my mods but i just can't figure out what this error message means. i'm new to making mod packs but i have tried making 3 separate mod packs with different mods but i still run into this issue and i am starting to think there might be a conflict between 2 different mods but again i have no idea since this is the only error message i get. any idea's?
