If you've grown her page to 2500 subs then I suppose that she told you in the basement to take a pic with your cock in it, after that you need to grope her every chance you can to make her feel more at ease with the sexual things, there's chances to grope her in the kitchen, at the park on wednesdays, when you take her to the mall on fridays, when she cleans the floor on mondays, and I think the scenes in the basement counts, I don't have the exact amount of times that you need to do all that but you'll know you've advanced the next time you take a photo with your cock she says she can't resist anymore and starts blowing you
Haha don't worry about it, I love this game and if I can help I will, now, which StarCon mission exactly? The one that appears in the questlog? I think it's just that, if you haven't been to StarCon yet then there's an email in the PC inviting you, you can talk with her about it or just go on weekends, but it's kinda expensive if you're not that advanced in the game, $35k, have Anna at 4 hearts, and 5k subs, that's all I know, it's not necessary to talk with her to complete it I think
Can you go to StarCon? Like, does the option appears when you decide what to do on weekends? If you did went to StarCon already then I think the option to talk to her doesn't appear since they talk about that before going for the first time, either way that quest is not that important, is there to let you know that now you have the option to go there, it'll be completed on its own when you least expect it
