FYI this is different to the replay glitches that I have seen on video's so far.
There is a glitch on Act 2 Finale where you can replay the finale but the host gets paid as well, a friend showed me earlier. I did it on PC but guess it will work on any platform.
I believe it only works with 2 players but not positive on this.
1 You have to start the Finale from invite only session.
2. At the start of the final cut scene where you are talking to the Agents the host disconnects from the internet.
That is it both the host and the other person get paid but you can do the finale again.
Alternative method from TyrionV
This will only pay out to the people that have joined but still a great way to make cash especially if 2 of you have the Finale open.
Set the pay to 85% to the person not hosting only 15% to the Host because the host will not receive money using this method.
You dont need to launch from invite only.
Easiest way to know when to quit is as soon as the minimap disappears hit your PS4 button and close app (or if on PC disconnect from the internet).
When you load back in youll probably find that your planning room is locked. After a while Lester will call you again.
Take about 12 mins for your mate to make $1m. Repeat.
I will be adding to and rewriting the entire post at some point to make things clearer and add some screen shots etc.
