Dead Trigger - have i completed it??

[StinkyDonk]

There are no more "Main Task" left, or whatever they're called. I just get told now to "complete tasks around the city" - so i keep doing these but no more main tasks appear, but at the same time there's nothing to say i've actually completed it.

I've just completed the one where you have to shoot the dot on the cathedral to open an underground door in the graveyard.
