Yeah it was Mo Combat! the rest of his mods work just fine on 0.10! Thanks for the reply!

Ok so I just had a quick look around, didn't see anything about this but I'm having issues launching the game after the 0.10 early update, as the title suggests I get an error near the end of the loading bar saying that it is unable to locate 'creeper' sounds or something http://i2.photobucket.com ...
