On the Advanced Spell Guide's Spell List ( http://paizo.com/pathfinderRPG/prd/advancedClassGuide/spells/spellLists.htm l )
Every entry for "Euphoric Cloud" is missing the spell name and link and just has the description.
The HTML looks like this:
<p><b><a href = "/pathfinderRPG/prd/advancedClassGuide/spells/euphoricCloud.html"></a ></b><sup>M</sup>: Fog obscures vision and fascinates living creatures.</p>
Notice there is no text inside the anchor tags.
