I finished the last quest where you must recover that glove from the imperial commision but for some reason i talk to ahnassi and the journal does not update. What should i do?

Be sure to ask her about "share a gift"
And make sure you still have the glove in your inventory.

Here's the command if you need it:
Journal "Romance_ahnassi" 95

It could be a mod conflict if you have something that affects her.
