Title: NullPointerException while crafting Wireless Redstone stuff

Version: 3.0.3/3.0.4

OS: Windows 7

Java Version: 1.7 64-bit

Description of Problem:

Whenever I try to craft wireless redstone receivers and transmitter items as soon as I put the last item into the crafting grid the item shows up but the client disconnects citing a NullPointerException...

This is ridiculous no one can use wireless redstone which is really needed for my server!

Error Messages:

No error report is being generated...

NullPointerException in my experience happen when the server has a different ID for the items you are trying to craft then what the client has. Check that your ID's match.

Huh, you're correct, different block ID, yet they're both base tekkit installs of the same version and therefore should have the same block ID. I've literally changed nothing but this system has one block ID server has another and all but one of the clients also has the servers ID...that's pretty messed up, what would cause this?

[Painfull]

Forge tries to make all the id's work with conflicts it randomly assign's new ID's to the items, that's why the item ID differ.

I see, any reason to avoid that? I assumed Tekkit was distributed with already functioning IDs so these types of conflicts wouldn't happen, and only 1/9 clients is getting this issue...
