Backup variables is ok, I tried. Actor2 will hide and assign to backup, then backup shows up, get another Actor2. It works well.
I don't know why, it keeps skip this:
Random
Sex(Player, Backup1, Backup2, Backup3)
Sex(Player, Backup2, Backup3, Backup4)
Sex(Player, Backup1, Backup2, Backup3, Backup4, Backup5)
Endrandom
When I write as below:
Sex(Player, Backup1, Backup2, Backup3)
Random
Sex(Player, Backup1, Backup2, Backup3)
Sex(Player, Backup2, Backup3, Backup4)
Sex(Player, Backup1, Backup2, Backup3, Backup4, Backup5)
Endrandom
First line will be triggered. The problem musts to be Random.
