Here it is, i can't attach xml files

Horde 10-90 in progress.xml

I have issues with horde lvl 15some quest in northern barrens "In Fungus We Trust"
It is use item on class quest and i get to location, i use item and it does the quest but it seems it don't register it properly or something because it just sits there atempting to use item it no longer have and well can't progress.
Now i did toy with objective count, gone trough every combination but it constantly keeps geting stuck there.
Please if anyone can solve this and if they do , do send me PM with FullCSharpCode so i can copy paste it, thank you :)
