I received an error message <Unable to Reach NPC - Please file BUG REPORT>
This occurred while grinding for items.
Specifics: Server three
I was grinding for a lightbringer helmet.
The I switched gear around, and noticed a need to grind for a Lightbringer staff (for Shayd).
I tried to start grinding for missing items, when the error message occurred.
Refreshing solved the problem.
Only reporting because the message said Please File Bug report.
