4J Studios is working to address a number of Minecraft Xbox 360 issues being reported since title update 9 went live yesterday.
The Minecraft title update introduced 'The End', featuring new Enderdragon behavior, climbable vines, fresh music and crafting options, among other features, but it hasn't gone smoothly for everyone.
Some Xbox Live Silver members are having issues loading saves, while other players have reported lag and lighting issues.
4J Studios has said in a series of tweets: "Getting reports of issues loading saves for Silver LIVE profiles in TU9. Seems disconnecting from LIVE resolves this.
"If you get "Connection to the server was lost" and are a LIVE Silver user, try disconnecting the ethernet cable. We are fixing this bug.
"We're also looking into the reported lag some people are experiencing in The End.
"We are aware of some lighting issues in TU9 and are investigating these."
Meanwhile, the PC version of the game reached ten million sales this week.
