This one's a bit tricky.
When you have equipped in an overload slot a glyph such as Greater Red Dragon Glyph or Greater Black Dragon Glyph; and you have slotted the OBP's Aura of Courage; and you change instance; the OBP will loose the effects of the Aura of Courage.
Note: The Aura of Courage buff icon remains, it's the actual extra damage that vanishes.
Workaround: If you are using an overload slot when you change instances you need to unslot aura of courage and reslot it.
To reproduce: Equip an item with a glyph in an overload slot, slot aura of courage, change instance to PE or Dread Ring, whack a target dummy, note no effect. Take out your glyph then head back to Dread Ring or PE and whack the target dummy there, note the courage effect is back.
Edit: Further testing suggests the glyphs aren't responsible. I don't know what's causing it. But until fixed, always unslot and reslot aura of courage after a loading screen.
