Play for an hour or so... just do quests, smash them out... at some point the pats disappear and don't show up until you /reload.

@Gogo1951 do me a favor... next time that happens turn on Questie Debug and run this...

/script QuestieQuest:GetAllQuestIds()

If that redraws the NPC PATH line... let me know.

I have a feeling these patrol paths are not redrawn when you switch continents/enter/exit a dungeon. Did you do one of those before you noticed they disappeared?

Never had another report of this and we were not able to reproduce this.

I just saw this bug the other day! (=

Was around the Assassin quest in South Shore. The pat path disappeared and then I confused that quest with a regular quest until I realized what was up.

Next time I see this I'll try and grab it.
