While doing the quest "No Stone Unturned," I noticed that my quest log failed to count one of the unusual stones that I picked up. I have all 24 in my inventory now, but the quest log only counts me as having 23. I revisited every site I cleared up to the point at which I noticed the discrepancy, which was at about 17 stones. After checking every site multiple times, I decided to get the next 7 and see if the issue would clear up. Now I have all 24, which I have confirmed by counting and recounting my inventory. I play on PC, and so I used the console to set myself on the next stage of the quest, which was to talk to Vex, but she didn't give me any new dialogue options. I was wondering if anyone else has this issue, or if anyone has any suggestions on how to fix it.
