Minecraft Alpha 1.0.13 addendum
Oh, and I forgot about the most important update!
* The client now checks if two instances of the game try to save to the same level, and quits if it does.
* Fixed
a hang/crash bug related to lighting. It wasn’t an actual hang bug, just an “each frame of the game takes
exponentially longer to render than the last” bug, which is pretty much the same thing.
As for the server, it’s extremely full, and is currently getting eight connection attempts per second..
