Thanks for reading!

 

nelson2tm May not affect anything, but I make my YML aliases differently:

Code:

main: me.nelson2tm.creativeinventory.CreativeInventory
name: CreativeInventory
version: 1.0
commands:
  creativeinventory:
    aliases: [ci,technicalblocks,technicalitems,tb,ti]

Bump

 

The section at the bottom of the error is most important:

You're trying to set slot number 18 on an 18-slot inventory, one past the end, which is the actual problem. The ExceptionInInitializerError part happens because you do this in a static block instead of your onEnable for some reason.

 

Thanks, next I need to better think in "computer" style. Counting starts at 0 and not at 1. forget that.
for helping SpaceManiac!
