I would need to know what you mean by it doesn't work, because testing with just Fixtus the Festus active showed it functional and I am seeing no errors in the mod editor.

Not working atm

I did do a table update while checking to see if any issues were being reported but it doesn't seem that there's any actual issues, and I just made sure these work recently in a quick Festus Campaign, so all should be fine.

Does this need an update?
