[MC-13224] World Doesn't Load, Also "Laggy" Sounds and frozen buttons. HELP OR PATCH PLEASE!!!!

So I opened an Iron Door and I noticed the buttons were "frozen" in the open position until I destroyed the door or both buttons. Then sounds began to lag heavily (playing ~1 second after the block was destroyed/created) and I couldn't pick up blocks after I dropped them. Then the game crashed, and now I can't open my world! Thank you in advance, inb4 duplicate, etc, etc.

EDIT 4/18/13 – When I try to open the world, it just takes me back to the title screen! HELP!

Crash report is attached

Kumasasa, what is that?

Nothing 😉

Just a snippet of the crash report for the searchability. Jira does not search in attached text files, only in comments.

oh, ok.

Is this EVER going to be looked into?
It's been a month and I've gotten zero information regarding this.

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

No answer, assuming no longer an issue.
