I been working on a custom crafting table, its is a 5x5 grid with 4 slots to hold tools. When I go to open the table I get.

 

java.lang.ArrayIndexOutOfBoundsException: 265

Yea, ok I feel dumb as hell. For some reason I thought I had to add to the others and.... yea... I got that fix, but now I am getting a null pointer. I can't wait for class to start up again so I know more of what I'm doing. Anyways, the error is as follows.

What is, "Ticking Player"? Does that just have to do with updates to the player?
