Confirmed.
If I do a fresh extract of Fetish 10.0 to C:\Program Files\Sony\Everquest2\UI\FetishNightfall\ I do not see chat bubble for quests or Griffon tamers, etc... I can see chat bubbles for simple chat or NPC comments that don't give you prompts to click. If I then rename the eq2ui_proxyactor.xml file and replace it with the one from this patch:

They work fine. It seems as if the one in the 10.0 release is bugged somehow. Hope this helps.
