So not sure if this is just a game issue or caused by the mod but there is a interesting exploit. Basically if your on your last interaction and request intimacy then say no the counter will hit 0 but you will still be in the interaction page. From there you can stay on that page as long as you like until you end it normally. Basically your able to use the teach option or anything else until you leave the page. No error or anything shows up sense your not stuck on the page.
