The quest I'm having problems with is the one where I have to kill the were-beasts. Each instance when I go to turn the quest in nothing happens. I try clicking the talk and get quest option but it just closes the selection box.

Ty in advance for your time.

When you killed the werebeast, did you get a text box that confirmed you completing the quest? You can slay dozens of werethings, but if you don't get the single one they want then it won't register as complete.

If you did get a confirmation text box then the quest could be bugged. This has happened to me before.

Alternatively, you could've had the quest where the "werebeast" is actually a bear or some other animal. If this is the case, you should still get a text box confirming quest completion.

Thank you =). I'll give it a try, and if the quest is bugged I won't accept it anymore. Ty again =)

Well, that's not to say it's broken every time. It usually works fine for me, I just had one instance of this happening a few weeks ago out of the dozens of times I've completed it.

Also, if you haven't, grab DFQFix from the UESP. I don't know if this quest is included, but it fixes a ton of others that you might run into.
