So, I had to make so many new games on Minecraft. Because, Whenever I save, and come back, This thing pops up saying "Connection server was lost" whenever I try to load it. It's been making me mad. I get so far, and I just have to let it go, because I know I will get the same thing popping up again. I made so many, and I can't even go back to them. I don't know what it means, or what I'm doing wrong. So, help?
