EDIT It could be Dynamic lights that could be crashing it. It does modify the same class xe.class as Forge.

 

After trying to log onto a server (which I'm able to get onto using a vanilla client):

Install order:

In jar: Minecraft Forge, liteloader, MC Capes & Cloaks, Dynampic Lights, OptiFine Ultra, Show Durability Mod, TabbyChat, KeepMyStats

In mod folder: Rei's minimap, Sphax 64x texture pack, Macro/Keybind Mod, CodeChickenCore, NEI, Inventory Tweaks, ArmorStatusHUD, DirectionHUD, StatusEffectsHUD, IngameInfo, Hotswap, Schematica, Monster Spawn Highlighter

It's definetly crashing because of DynamicLights. The fact that both, Forge and DL, edits the xe.class and the crash report shows there's something up with this class (it's missing a method) confirms that.

Ask the mod author, if he can make a patch for Forge or if he could move to Forge (then he don't need to edit base classes because of the Coremod functionality).

Sorry, should've looked more into it. It turned out that, yes, it was Dynamic Lights.

 

AtomicStryker posted an update that works with Forge 6.0.1.350 - http://www.minecraftforum.net/topic/184426-142-dynamic-lights/page__st__2140#entry18865544

 

Thanks
