I assume that it's a burgular problem because as of late, I've had a string of robberies and it's only happened with the burgulars. The new mayor of Veronaville cut the VVPD's budget and I'm getting robbed in almost every house...okay 3 but that's 3 more than I've been robbed in months!
Anyway, my Sims become furious with the burgular getting an instant -100/-100 relationship with him/her and then when the furious state wears off, the relationship score turns to the positive integer. Meaning that a -89/-80 score turns into 89/80 and one hug away from becoming best friends with the person who violated and traumatized you, not to mention the bitch that stole a dress rack from your home boutique which is IRREPLACEABLE.
The last time I was robbed, I don't think NL had come out yet so I don't know if this is a NL glitch or an OfB glitch.
