Delta 72 Knight

So for me it would be like this? fluidOil.setBlock(blockOil); And it would go right in place where? I put it below my GameRegistry at the bottom of the PreInit Event and I still get the same error I have tried it in a few varied spots and have gotten the same or little difference in result.

I hate posting messages like this because I know they annoy me but I really can't figure this one out. While coding to add a liquid today(Just one that looked like oil) I was having difficulties in getting one to work, I finally got to what I thought was the solution. Then it crashed and I can't figure out why, I can read the errors okay now thanks to my experience but I can't find out where this one leads, or where to fix it. Any help is appreciated! Here is the Whole crash report https://gist.github.com/anonymous/7dd18baf88c94218929e And if you want to look through my code here it is: This is the main class https://gist.github.com/anonymous/900a021870557211bd66 and this is the block class for the liquid https://gist.github.com/anonymous/f856dcdcc4f3574038b3
