I've been trying to make a server for me and my friend, but everytime I create my character it'll either lose connection, or say a file was not found on client. First scrap armor and armored vests were the ones causing the file not found on client thing, but now the server just crashes after a black screen. Is there a way to fix whatever mod is doing it? Almost all of the mods I have enabled I'd like to keep.
