When I try to turn in "Memento Vitae", it says: "[Mission] Unable to resolve mission "[Zone Wide] Memento Vitae". [Inventory] Inventory full." Since it is not the visible player inventory that is full, I assume it is not passing a token correctly.
Many thank yous to the The G&T Show for the Holo-Leeta doff!
But I have since then notice the pumbing missions are inconpletable too, due to some of the items to place are behind a invisable wall in the borg staging zone around the central pillar, or in a corner that your character cant reach to them. Like at the temple where you start the hard mission. there is one on the left side of the hard entrance where it is tuck in. You can see it, but cant reach it.
I end up having to drop it since, it almost like the contact points are badly placed on the map.
