I have played MM7 very long time ago, but never finished. Lucky enough, I got new CD's and started playing. This time I want to go through it! 
But there is one problem. I did a quest for rescuing a spy and a quest for retrieving fort plans. I could see this in my AWARDS page. Thats ok so far. Then I got a quest to find a trumpet and give it to prefered side. I had that trumpet and went to castle Harmondale. And my quest book blinked as if I had a new quest.
I clicked the book, but there was only a number 0 instead of a quest. A zero.
I gave the trumpet to judge Grey and I didn't see that zero any more, but there is no entry in AWARDS list about completed quest. And flamestryke site says something about new history book entry - I do not receive any new entry until judge Grey dies a month later.
I reloaded my old save and replayed the trumpet quest in many ways - I gave to elves, to humans, didn't give to anyone, I tried to enter the Harmondale before I gave away the trumpet, or after that - many different combinations. I gave away the trumpet in Harmondale castle, in Erathia and in Tularean forest. All possible combinations. But I always see that Zero in my quest book and do not see the finished quest in Awards list.
What's wrong? What is the right way of doing this quest?
