Two questions about traits

First of all, the temporary traits that a general gets from sieges, such as "depressed by siege", "grumpy from siege", "angry from siege" as well as "indifferent to siege" do not disappear. All of my generals who have been under siege still retain these traits. The hidden antitraits that I found in the export_descr_character_traits document do not seem to be working.

Also, I often read the EDCT, EDU and EDA, hoping to finish them all and have a more intimate and complete knowledge of EB traits, so I can use it to my advantage in gaining traits for my generals. Just today I was doing my almost-daily reading of EB files when I stumbled upon these couple of traits:

Malrubius is one of the members of the EB team who works on traits and Therother is another notable member, although I am not quite sure what's his position in the team. So anyway, what do these traits mean and do? Or are they just Easter eggs put there purposely?

These are testing ancillaries. Both Malrubius and Therother have worked on traits&ancillaries, and they were using these to more easily check whether triggers work as intended.
