Negative bonus for Eco Guru

oops636 Was the Sim promoted as a result of a chance card, or just by having all requirements met (skills, friendships, etc.)? 

Are you able to reproduce this bug with another Sim in another neighborhood?

I think this is an old bug. I remember that I thought it was intended, because "you are ought to save the nature and therefore give not take". Nevertheless I quit without saving and removed all the money from the family funds. xD Can't remember if that helped.
