so i have it set to 5.25 for RAM and launch the FTB Ultimate pack wait for everything to load and get to the title screen i create a new world or i try to load an existing one and in the console it goes through generating the world but then when it is done in the console it says it is stopping saving players and shutting down server. to fix i have tried re-downloading the pack pack and removing mods that could be causing it and nothing fixes it. May anyone give me insight
