Hey, it looks like you are trying to run it as a server. Gee, I wonder why it crashes when there's two clientside-only mods included. No clue at all why it crashes...

      I also have the problem that some blocks just do not have any/the right textures. This is really annoying but the mod seems still playeable with those texture bugs. But the crashing makes it impossible to play.
