Wow...that was crazy, but I got it....
never needs to be: noun and imperative verb
say needs to be: noun
die needs to be: imperative verb
I would play around with this some. This will obviously totally mess up your vocab for the rest of your game if you ever intend of using those words. Also, die and the death script might have issues with each other. I changed the words to the above and it worked...that doesn't mean it's the only way it will work.
Good luck, hope this helps.
One more thing, don't forget to always rebuild your resources after ANY changes you make. Don't forget to save the vocab file to the game too...I do silly stuff like this all the time....
