the neural degradation only lowers on the pawn itself when they are sleeved, not on neural matrix management screen or when stored in the matrix either.

when I go to modify the stack it acts like the pawns neural degradation never went down no mater how much time passed or what the neural degradtion is at on the sleeve itself.

some times after modifying the stack when its like this the pawn gains no degradtion either if the amount it would have given is lower then what the pawns last degradtion was at so lost as its current degradtion isn't at zero.

I think this might be a mod compatibility issue with something like "Character Editor" or something
