WotLK Shadowmourne quest problem

[Oxeri]

I can not deliver the first mission of Shadowmourne, despite having all items not let me give .. I have afraid to leave the mission and take it again because I can lose bloods ...

[Shred]

I would open an in-game ticket explaining the case

Bloods shouldn't dissapear, you can even put them in the bank and leave them there as you abandon and re take
