I found 3 glitches I posted in a separate thread, but now that I realise this thread exist, I'll post them here:
The first of them all is regarding a quest in which Lisbet, shopkeeper in Markarth, asked me to recover a statue of Dibella for her. The main problem is that I had to kill her since
Spoiler she was a [censored] cannibal
and now there's no way of finishing the quest, being stuck with an awesome, 2 pounds heavy, gold statue I can't get rid of.
The second problem, which I assume will be a bit more widespread, is triggered after finishing the "No one escapes form Cidna Mine" quest, in which I
Now, guards on the streets of Markarth yell at me "Halt, in the name of the jarl", but do not even try to arrest me unless spoken to, and even if I tell them to send me to jail, they won't do so, being stuck in the same conversation I only can exit by pressing "B", after what they completely forget what they were doing and keep wandering (This also means that even if I commit crimes I can leave unpunished).
Last of them is related to the quest "In my time of need". After finishing It on Saadia's side, redguards keep appearing in the wild asking for a redguard woman, and two Alik'r warriors are standing any time of the day at Whiterun's entrance (They do nothing, though, and answer with a "Yes?" or "How can I help you?"). I must say, though, that I didn't talk to kematu before killing him, as he attacked me without initiating a conversation for some reason (By then I didn't know that was supposed to happen).
