there seems to be a bug that looks like it has something to do with traits
XML RimWorld.ThoughtDef defines the same field twice: nullifyingTraits.

Field contents: Kyulen.

Whole XML:

<ThoughtDef><defName>AteCorpse</defName><showBubble>true</showBubble><icon>Things/Mote/ThoughtSymbol/Food</icon><durationDays>1</durationDays><nullifyingTraits><li>PickyEater</li></nullifyingTraits><stages><li><label>ate corpse</label><description>I had to eat the flesh of a dead creature without even butchering or cooking it.</description><baseMoodEffect>-12</baseMoodEffect></li></stages><nullifyingTraits><li>Kyulen</li></nullifyingTraits></ThoughtDef>
