So I just installed the latest version of forge (4.0.0), and the game starts just fine. I can run around, punch blocks, do pretty much everything that you can do in minecraft. However, whenever I try to attack a mob (hostile or friendly) I get an "internal server error" and it disconnects me from the server. However, I'm playing on my singleplayer local map, so I don't quite understand why it has to kick me from a server at all... Any help on this issue is appreciated.
