Hello, I have been playing Skyrim SE on XBox1. I have a few "glitches" that I need some info/help with. 1. Immersible Wenches. I had to rescue 5 maids for the quest. I asked one to wait, so she would not die. When I came back, she was gonzo. I even went back to where she was held hostage. 2. Multiple NPC's. I have 1 slot left from 28. I have 5 with me. Where did they go? How do I get them back? 3. I was doing a quest for "dwarven shield of blocking" for Clacelmo. I dropped it somewhere. I even enchanted a new one and still cannot complete the quest. Thanks.
