When entering the Nether - Mobs don't move nor attack the player, switching between difficulty modes and between creative/survival makes no changes. I'm able to hit the mobs but they don't react - Let me know if theres any other info you need

I don't support any Forge version higher than 47.1.3. Please test on that version.
