Hi guys, I'm crashing on joining.

location: x=3848.32, y=160.20, z=6825.32
situation: getting on a mule

java.lang.IllegalAccessError: tried to access field net.minecraft.client.gui.GuiIngame.field_73845_h from class com.bioxx.tfc.Handlers.Client.RenderOverlayHandler

Help much appreciated, save the mule if you can!
