When i start Forge in my minecraft launcher it goes well at first but then after a while when it starts it just shuts down and says " It looks like you are using an unsupported modified version of the game" and "The game crashed whilst initializing game" and it just won't work. I have checked so that i have uptdate 1.12.2 on forge,minecraft and all the mods (4) i downloaded so i don't know what could be wrong! Here is the error thingy: Error: java.lang.NoClassDefFoundError: com/mia/craftstudio/IPackReaderCallback
