Add FML3 extra packetID 5 and 6 recognition based on https://github.com/MinecraftForge/MinecraftForge/blob/1.18.x/src/main/java/net/minecraftforge/network/NetworkInitialization.java Changed the way of selecting FML version for "Force Forge" from forced FML3 to game version based. MC 1.12 and lower: FML, MC 1.13 to 1.17: FML2, MC 1.18 and greater: FML3 Edit outdated links in comments: Accessing the link below will result in a message that the file cannot be found https://github.com/MinecraftForge/MinecraftForge/blob/master/src/main/java/net/minecraftforge/fml/network/FMLNetworkConstants.java Presumably it's version 1.13 based on the original commit and issue, then change to https://github.com/MinecraftForge/MinecraftForge/blob/1.13.x/src/main/java/net/minecraftforge/fml/network/FMLNetworkConstants.java https://github.com/MCCTeam/Minecraft-Console-Client/issues/1184
