Something is wrong with the server network, or your local network. Somewhere along the line the network is having problems, which makes you disconnect.

Anyone who wants to craft has te problem... so could you tell me what is wrong with the server network, or aren't you able to read that?

Now, where in this do you see anything that has anything to do with crafting? There is something on items, but there is a network issue, also a java.lang.NullPointerException Problem, so you tell me how that there is ONLY crafting problem, NOT ANY errors with the network. Also you should try to show attempts in the error report, only one won't do it, especially with something so open-ended as crafting.
