if you want i can leave the entire crash report

basically whenever the game loads up i join and i recieve this crash:
Error: java.lang.NullPointerException: Rendering item
i checked the folders and believe it to be caused by this:
A detailed walkthrough of the error, its code path and all known details is as follows:

-- Head --
Thread: Client thread
Stacktrace:
at p455w0rd.danknull.client.render.DankNullRenderer.renderItem(DankNullRenderer.java:107)

/dank/null version?

DankNull-1.12-1.4.33
i managed to (because it is a server) get someone to setup a perpetual killing machine with /kill that killed me before i rendered in which sorted the problem of me crashing, but once i broke my grave - Error: java.lang.NullPointerException: Rendering item in world

thx..i already have this fixed in dev..just gotta get this update out
