Ill explain. I was doing some thing where i found a series of books ("journals". Im using the word only to refer to these items, not the actual journal for the player character). Each one was unique, on the body of an NPC. What would happen is I'd go to look the NPC's body, and before I could pick anything it would open the journal. That itself was odd cause normally you have to move a book from a container into your inventory, and then read it manually.

But after this, I wouldn't have one of the journal.. I'd have two! totally identical, showed up as a stack. This happened all four times the bug occurred.

A second, probably related thing happened later on too. when caught by a guard, he gave his normal "pay or go to jail" dialogue... But the dialogue immediately closed and he attacked me. This also occurred a couple times.

I don't know what caused it, why it started, or why it no longer is happening. Im just putting this here for the record, basically. It seemed weird.
