After the first date with Millie, you head back to obtain the Casino Card from her. You have 2 options at this point
- Kill Millie. Soon after, you'll receive a phone call in which you'll enter Millie's home and take the Key Card from her house.
- Date Millie. Aquire the Gimpsuit and pack a couple points in muscle. If you're not muscular enough, she'll reject you. This'll take a couple times but once you hit about 40% - 50%, Millie will call you and you'll come to get the Casino Card from her and her Car keys.
In any process to get the Casino Card, you'll need to meet Millie for the second time. Either for sex or for the kill. But Unexpectedly, there is a bug in which Millie doesn't appear home during her regular hours of 2:00 - 10:00 and 14:00 - 18:00. To fix this bug, simply walk to the neighboring house to the left that has a car in it's parking space and get in. Then simply get back out and check for the red mission circle. If it's there, then go and DO her or KILL her. If the circle doesn't appear, go in the car and get out again. Repeat until the circle appears. This will only work during the hours of 2:00 - 10:00 and 14:00 - 18:00.
Tips
Remember, if you want to “DO” Millie, you best get the gimp suit on. It gives you a little extra in points so you don't have to “DO” her as many times to get to your goal amount
Make sure you've dumped your previous girlfriend!! Millie won't come out until you've visited your old girlfriend and make sure your old girlfriend dumps you!
After getting dump by your old girlfriend, save your file again but in a separate file. DON'T OVERWRITE YOUR PREVIOUS FILE! Keep this for insurance in case some bad happens. I recommend you save 2 files after every successful mission to avoid starting over if you've goofed on something.
This worked for me, let me know how it goes .
