I can't complete the main scenario quest "Unsolved Mystery" even though i have completed all of the objectives for it.When I was trying to finish the quest by giving the items "Ripe Corpse" (3x) I had a electricity cut off.After logging in I wasn't been able to complete the quest and when I looked into my inventory items "Ripe Corpse" (3x) were not there.Because of that i can't complete that quest

Character Name: Duff Man
NPC name:Isembard
Area:Eastern thanalan,Camp Drybone
Steps:
1.Started the main quest "Unsolved Mystery"
2.Completed it's objective
* Objectives
Retrieve ripe corpses. 0/3
3.Returned to the camp and tried to hand in the quest.
4.Electricity went off before the quest completed.
5.When i logged back in i didn't had the items "Ripe Corpse"(3x) in my inventory and couldn't track back and retrieve them again.
6.System says the quest is available to complete but when i try to complete it it shows a dialogue and nothing happens afterwards.So i can't complete without (3X) "Ripe Corpse"

I want to go on with the quests but due to this bug i can't please take care of it.Thank you.
