I recently made a new modpack for 1.10.2 and everytime I create a world, it comes up with the error "Forge Mod Loader detected that the backup level.dat is being used." I've tried delete all the saves, reinstalling the whole modpack, but none of it has worked. After I click yes it will just stay on "Loading world". I tried letting it sit for about an hour but it still doesn't do anything. After I close it with Task Manager, this shows up in the crash-reports. I am not very good at detecting errors myself, but it seems like it has something to do with the coremods. I tried moving them to the coremod folder but it just makes them go missing. I am still pretty new to making modpacks. If someone could let me know what I need to do I would greatly appreciate it.
