Opportunity Bug: charisma "find a friend"

[whismerhill]

hello,
I have this opportunity for the charisma skill
 "find a friend" : build friendship with *nameofsim* => is supposed to give charisma when completed

however I can't seem to be able to fulfill that particular opportunity
the sim in question is a mixologist and it was really hard to befriend her (only available between 6AM to 9AM each day ...
now I'm finally best friend (80.6) and the opportunity still sits there

Abandon the opportunity.
