Im on the Super Earth server
Wait is the server back up? Because I still can't get on... Idk maybe im doing something wrong.
Soon as this is fixed, I see no issues updating servers, but making thousands of mossy cobble, diamond blocks, gold blocks etc ruins the game in multiplayer
I even made a machine that duplicated the sand blocks.
i see a bed
Note that was "fixed" in 1.6. As to how you got it to work in 1.6 is another story, you are not saying something here.
I will bet you a full chest of diamonds that you used a world with mods that didn't update to 1.7. Anything stored in a chest that comes from a mod which doesn't exist due to the update is going to cause your SSP world to crash when you try to open that chest.
Either update the mods, or live with the consequences and start a new world. Perhaps it is a "bug", but life stinks, doesn't it? BTW, this isn't new to 1.7 either.
