It's funny to see that you can get at each others throat quite fine without me
Ok jokes aside. About the Amy nightbar drink event in the ladies room:
- Amy needs to be in her basic night dress (the blue one)
- then there is a combined affection/love check. if you pass it, she will put her hand on your leg
- then you need to "compliment her"
- then there is a player charm check, charm >= 3
- then guy asks her if she wants another drink
- then a very high lust check on Amy: lust >= 80
- then a very high love check on Amy: love >= 75
- if both checks are ok, she goes to the ladies room and you can follow her some minutes later
It has absolutely nothing to do with which bug fix you are using or if you installed bugfix 1 before 3 or whatever.
