Portal no longer available - Bloody Harvest side mission

Hi All, I was completing the bloody harvest side mission from Maurice, i killed all the various ghosts, collected sufficient Ectoplasm, and then took it back to Maurice who opened the portal to somewhere for me. Unfortunately real life called and i quit the game, upon re-entering the game it appears that the portal was now no longer open, the side mission is gone and i can't seem to reengage it with Maurice.

So i think my main character (only one at level 50, again real life) is now unable to take part in any of the special event nonsense. If you need to quit, make sure you go through that portal first, unless anyone has any idea on why this happened and has a way they could help. Thanks
