I finally get Cait up to a trust level where she tells me about her chem addiction and we go off on her quest at Vault 95. All is good, until we're just about at the room where the equipment is that she needs. Cait disappears, I can't complete the quest without her.
I find her back in the Combat Zone. Only now when I go up to her, I get the prompt to press 'X' to start a conversation, and when I do, she says a quick line and the prompt remains the same. I can no longer engage her in a conversation, I can't get her to join me as a companion, can't trade with her, no interaction at all.
I've even tried waiting, so far for more than 96 hours, and no change.
Anyone else have this problem? If so, how did you fix it?
