Is this Hang in game a bug?

[DracoHeart]

While playing very fine in my server with a few online players, I played for about 2hours in the game. Suddenly, the game just freeze. And the sound keeps replaying the same thing. Is this a bug or something wrong with my computer? Unstable?

I don't know, I had the same problem with 1.1. With 1.2 I still have it, but it's a rare occasion. This is one of those crashbugs which they don't know much about.
