The game can startup normally, but when I try to create/enter a world,it will remind me"Unexpected packet during modded negotiation - assuming vanilla or keepalives : net.minecraft.network.play.server.S00PacketKeepAlive" and I can't enter the world. That happened in my modpack which contains fastcraft1.25+optifine E7+coretweaks+bugtorch+foamfix+Neodymium and a lot of other mods.
