I'm sure everyone's curious and irritated; Why is AS1 always crashing and being offline?! Is something broken? Does the server break from the player count? Is it crappy connections?
The server normally crashes due to someone creating an event which causes the server to crash, which is why the server rolls back a small bit, to make sure that the error is removed. It's normal, and should be expected with the sheer amount of people attempting to experiment with different blocks and items.
