I've had that as well saying the overall task is complete when I stil need an item or two on the overall title line. I guess I'm just hoping that what I'm noticing on the sub-lines isn't a bug
I hate it when I feel like I'm killing a thousand things and have no idea if I'm ever going to recover the item I'm looking for.
For example...on the assasin quest it would've been nice ot see that each time I killed an EITC officer my completion was going up 25% so I would have known the fourth try was going to be my lucky charm.
Overall I know its probably a bug...but here's to wishful thinking it isn't
