QuestUnits.xml
The Talax unit looks like some copied and pasted the same information within itself. The XML tags aren't closed because of this.
Line 312 you'll see where the <UnitType> element shows up right next to the recruitment text.

I was looking for a tool that would allow you to validate / check for files that aren't well formed. With oXygen I was able to create a new project, import the \data folder, right click and select "Check Well Form". It parsed through all the XML files in less than a minute. Visual Studio provided better information, but I can't figure out how to make it check all of the files without opening each file manually. That's where oXygen rocked. At least now you know which files to open in Visual Studio (or a different tool) to review.
