Hopefully fixed for the next release.
Originally, the cock sock will only make the bubble after waking up from a non-dream sleep, on the ship, and if not interrupted by another event. That function should be retained, but now any event that returns to the normal sleep sequence, with or without dreams, on or off ship, should now be able to produce a bubble. Any event that does not return back to the normal sleep sequence (such as sleeping in Taivra's Chambers) will continue to ignore the bubble making. So hopefully this catches the most cases to make the underwear more widely usable.
