Define "making the game crash." Crashing when it starts up? When you put it on? Post the crash report.

When I start up the game

How about providing the crash log? We don't have diesieben07's magical code reading mind

Oh, now I see the problem. You are trying to use a tool material when it is still null. Add the toolmaterial before your item.

Thank you amazing how that 1 line could mess up the whole thing
