As ainz had checked Shalltear's system levels, it is shown that her levels are fixed and did not change, instead she lost some memories, this cause me to thought up of a personal theory that I think that the author may be trying to convey.

Shalltear did tell Brain that she was borned (created) to be so, so her skills should be fixed to the basics even after she was "reborned", But what did change and can be proven is that NPCs can learn and adapt to new things just like humans, shown by cocytus being able to learn from his mistakes and Ainz being able to learn new knowledge about fighting as a warrior from cocytus. Therefore, I agree with one of the Anons above saying that Cocytus may be able to learn new skills, but if he died and got revived, he may get back to his pre set settings while losing what he had learnt (memories)

Thus this may be the reason and cause that if the NPCs die and revived, what they lose is their mental experience (memories) while keeping their fixed physical levels (born and created to bo so) in reality of that world. But This is just my personal theory as the reason why NPCs loses memories might be due to other reasons too such as side effect of being mind controlled, but if even if it is otherwise, it will still be a lot easier to explain.
