The game crashes when i mess with the config files. Also, for some reason it crashes when I disable the Mechanical Toolbox on the config.

Artisan Worktables Config.zip

com.google.gson.stream.MalformedJsonException: Unterminated object at line 15 column 8 path $.list[0].oreDictKey

Looks like you've got some invalid json.

The only json file that would cause that is:

artisanworktables.module.Tools.Materials.Custom.json

I'd check that.

Also, in the future, please use pastebin, gist, or an alternative to post your config files.

I've remade the config files and was able to fix the crash. But yeah, my bad on the config files.
