Hey guys, so this is my first post.
Recently I've made myself a personal modpack so that me and my friends can play on a server. I have "forge-1.7.10-10.13.4.1614-1.7.10-universal" by the way. For some reason though when I open up the forge universal Minecraft Server thing it gives me a string of messages where it says some mods could not be found or what not, with it ending in the whole thing closing down automatically. Does this issue have something to do with some mods I have not working properly or some other issue.
P.S. I also tried opening it with the actual minecraft_server.1.7.10 which did let me into the world however made so that modded blocks or items could not be placed and also not be able to generate naturally into the world.
