Attraction score error

One of my sims keeps loosing his aspiration. Once he has no aspiration assigned, he starts spinning aroung and glitching. No interactions with him are possible. Upon typing "boolprop testingcheatsenabled true" an error pops up as game is not able to recount an attration score for him, as he has no aspiration which is vital when calculating for example chemistry. Only thing that Temporarily resolves that problem is, reasigning his aspiration via InSimenator, which is a mod, however, after a whie, the problem keeps occuring again.
