I'm using forge 1.8-11.14.0.1273 (the server and client) and a Friend of my who hadn't forge installed could login the server and everything was just fine, but when he crafted a acacia fence it transformed into an oak fence. So I ran the server without forge and everything worked just fine. Could it be a forge problem or it was because he didn't have forge client installed? Sorry for my bad English
