Not having server connections in single player?

I don't really know whats going on but for some reason the game will often say 'connecting to server' and the most recent blocks i broke just reappear and need to be broken again, its as if im connecting to some kinda server but I am infact playing singleplayer alone, I don't know why this is happening or if its a specific mod but if someone could tell me a fix that would be great
