EvilOwl Posted March 13, 2015 Share Posted March 13, 2015 (edited) java.lang.RuntimeException: java.lang.NullPointerException at cpw.mods.fml.relauncher.CoreModManager$FMLPluginWrapper.injectIntoClassLoader(CoreModManager.java:130) Forge swallowed something bad, probably a dev version, bad or corrupted mod. Where did you get those mods from? 9minecraft? Those don't look like the official versions. There are safer places to download mods: curse, curseforge, minecraftforum. Replace the mods with their proper versions and recheck. Edit: typo Edited March 13, 2015 by bochen415 Link to comment Share on other sites More sharing options...
Discord Moderator plowmanplow Posted March 13, 2015 Discord Moderator Share Posted March 13, 2015 Your modpack is configured to be for MC 1.8.1 on the settings page. You need to select 1.7.10. All of your mods are from illegitimate sources. This post on getting mods may help you: Link to comment Share on other sites More sharing options...
