I have a Problem... i have a expertish Modpack, and Players play through different Stages. My Players are in Stoneage, and have no possibility to eat different food. I just want to add Hungeroverhaul in a different stage, so Players get started with Hungeroverhaul in a different stage, other than at the very first beginning. That give the Players some time to gather Resources and Foods.
