i created a server to minecraft alpha 1.1.2_01 but all the mobs and i are immortal. how can i fix it?
I love that you're doing this, but unfortunately there's no way to fix it. Alpha 1.1.2_01 was VERY early testing and it didn't work properly. That being said, you could upgrade to Alpha 1.2.6, which works a lot better.
i will try, thanks.
