I'm also having the issue where the corpse in the morgue can't be looted. I have TSLRCM (1.8.4) and I'm using the 1.3 version of this mod. I also got the "Error: Destination file "Modules\103PER.mod" does not exist at the specified location!" message when I installed it, so I installed it manually for good measure, I don't know if it's related.
All that aside I love the idea of this mod and what I've seen in the first few rooms looks so much better than vanilla.
