Quest bug. (Mount Blade)

I will not delay - that's how it is:
Spoiler I took a task from the guild master in Sargot, I had to find a gang of robbers and fill it up, I did everything, but on the way back, instead of passing the quest, I took another one from the local king. As a result, I did not catch that moment and loaded the save (!), And here is a trick. A kind of time loop, I don't even remember whether I handed over the guildmaster's quest or not, but the fact is that (and it looks like this) maybe I handed over the quest, survived, then loaded again (after submitting the quest), but the quest remained hanging in magazine. Of course, then I did not find any bandits, which is why the quest failed. And now ...
When I take a quest to capture a gang of robbers from a guild master of any city, they stupidly do not appear.
I hope I have painted it clearly (I doubt it). Background under the spoiler, succinct. If anything, I'm ready to pickle.
