Somehow, you're having a different Slot class then I.
But it looks like somehow the slot inventory is null.
Figure out how you created a clot with a null inventory.
That returns a fully translated string, you can do whatever you want with it.
It grabs the message from 'death.entity.entityname.name' in the languages file and translates it, you could do whatever you want...
I just sat down and tested on the latest forge, levers and buttons work fine in Multi player.
Perhaps strip down the mods you use until you can identify which one it is.
Its a bitch to get modders to do things the correct way.
And its even more of a bitch to force there hands.
I Will be adding such a fucking system in 1.3
Quit fucking asking for it like its a brand new concept like you're the only one to ever think about it.
You state that you don't know why its so hard, you shouldn't be posting if you don't know.
You installed computercraft in some place
that makes FML think it is in the mods.computercraft package.
Zip your .minecraft folder and send it to me.
Don't feel like arguing over things that can be proven fairly quickely.
Ah, ya thats cuz you're doing something really stupid and putting everything into the jar.
Thats what MCPatcher does...
Don't use MCPatcher use the plethora of other tools out there that install things properly, or install things yourself.
Get the exact versions of the mods you're using.
And the exact recipe you're trying to use.
Nothing changed with the Ore Dictionary that should cause anything like this.
Marks the blocks as dirty {there is a function around there somewhere} or use notify.
Either way if you do it in one go, all the changes will be gathered up and sent to the client in one chunk.
It should unless they updated to the new Ore system.
The ore system is backwards compatible for the time being.
But if they used the new system, it's just one recipe that works for all the diffrerent types of ores.
