For the Maidenholm quest, Moon Juice Leech, I killed the two constables that we're inspecting the body. I then inspected the body but there was no indication telling me as to whether or not I failed the quest. The map marker is still visible and the quest is still listed in my current quest log. I believe I received the skill points for the quest, but the text is red instead of black. I have not failed a question before and don't know what that looks like, but I did attach two images of the quest log and map. I'm playing on a PS4 Pro, forgive me for the poor image quality.
