I will check it, but there are some posisbilities. Maybe you passed enough time for the action to pass the hole time and start again. Maybe it's a minor bug. I'll need more info. Eg: The action between the 2 chars, the remaining time for the action, the amount of time you passed, If you were speaking with any char...when you pass time and one of the people having interaction with someone there is a chance time doesn't pass for them (the remaining time of their talking/having_sex stays the same), what's the idea behind it or is it a bug
But it's interesting.
