Yeah, I had that happen with one of my mummy encounters too. I think it's strange though how there aren't any interactions that the sim can take with the mummy snacks....like "offer a snack"...."throw it at the mummy"... "eat in front of the mummy"... something...anything. Instead, you just have to have them in your inventory and the mummies can take them at will. (or not) I stocked up on mummy snacks while in Egypt this time....bought 40 of them!! And out of all the mummies she's seen, (there have been like 6 so far) only 1 snack has been used. I think that must have been the one who wasn't very nice. All the other mummies she's encountered seemed to like her for some reason. LOL
