I play my mine craft on a Macbook Pro, Recently I had gotten it to work again, And saw my old servers. I played on a couple of them for awhile, But none had nothing much on them. I had a giant list of Multiplayer servers as that is all I played on. Recently, I signed on and realized that none of my Servers were there. I thought that maybe it was from me changing my username from chloe4068 to ScarletWolfGames, But even with the name change my servers were still there. I went to download an adventure map and Put it in the saves folder, In which, My old servers were still on. Well. My single player ones anyway. I thought my old servers would be back, I played again, They weren't there. Before I had played I had deleted copies of mine craft folders with the same things in them, well, same folders. I had then lost my servers, But seeing how they still exist but aren't in the game confuses me. Any help?
