Hi

I've just convinced Cassidy to sell her caravan business, and I've informed Alice McLafferty that Cassidy has agreed to sell.
However I can not progress the quest any more. I've recruited Cassidy as my new companion. But I've exhauset all the speak options, yet the quest still doesn't continue as outlined in the quests description at the Fallout wikia. When I speak to her, she just tells me I'm an [censored], and I have no idea why she is so mad at me. I have only one chance at speaking to her. The second time I speak to her, see leaves me, and I can not speak to her no more. When this happens I do not get the message that the quest has failed, yet it is grayed out along with all the other quest I've completed.
The last checkpoint in the quest I've completed is "Return to Cass and see if you can get her to part with the title for Cassidy Caravans". How do I continue this quest?

PS. I've completed the quest Can You Find it in Your Heart? before I conviced Cassidy to sell her caravan business.

I BELIEVE she leaves your companionship if you have low NCR rep/bad karma. Do you have both/either?

Try raising your karma first to at least neutral, and then speak to her. If your karma is below neutral, she won't have all the speech options and will leave you after the third attempt to talk to her.

You guys are right, my karma is at -1000, which I believe is the lowest possible. Who can resist thieving and lockpicking? :ninja:
When I rewarded myself a positive karma value, Cassidy suggested the detour as soon as I spoke to her.
