Issue Description:

When using /mt recipes, if a recipe exists with a null output, the command fails and doesn't finish dumping recipes. I encountered this problem with Davinci's Vessels 1.10.2-0006, which has an improperly registered recipe.

What happens:

/mt recipes fails with the message "An unknown error occurred while attempting to perform this command", and minetweaker.log stops in the middle of the Davinci's Vessels recipes.

What you expected to happen:

For the recipe to be skipped and /mt recipes's output to continue.

Script used:

No script involved, only /mt recipes

Minetweaker.log file:

minetweaker.log

Affected Versions:

• Minecraft: 10.2
