Crash when pressing play

[Weaselbee]

Minecraft was acting fine, but a mod required an update to the latest version. I updated it, changed the Launch Option to the new version, and now whenever I click play it immediately crashes.

something is causing the extra --version argument to be passed in. As its not something that happens on our end alone I must assume that its LiteLoader adding the extra argument. Not sure why.

Yeah it's something with LiteLoader, but there is a fix remove the LiteLoader jar and edit the forge version json, add 

{
"name": "com.mumfrey:liteloader:1.6.4",
"url": "http://dl.liteloader.com/versions/" 
},

to libraries and add

--tweakClass com.mumfrey.liteloader.launch.LiteLoaderTweaker

to minecraftArguments before the forge tweakClass. Basically loading and init LiteLoader before forge
