Upon crafting the Wireless map and placing it in my inventory, the client crashed. http://pastebin.com/vZdbrayy here is a copy of the crash report.
Also on a semi related note. is there a reason that you do not use a more formal bug tracking system than a forums thread? Using Github or some other method of tracking bug reports would not only make things easier on you the programmer, but also make it much easier for users to be able to look up and see if the bug they are reporting has already been addressed or not. At present there are 1175 pages on this thread, and to expect someone to even look through half of them to see if an issue has already been addressed is unreasonable.
It would seem that as long as the item is in the inventory, it continues to crash the client. I just restarted my client, reconnected to my server, and before the world loaded on my client it crashed back to desktop again.
