I think I got the latest update (a couple of days ago). I can't leave the room because the exit cannot be passed. I can walk to the exit and then, that's it. Maybe I should add something. As a not-too-young person (not sure whether that's really the reasons) my reactions were probably too slow for this game and in order to make it at all; I had to edit the corresponding json file and deleted all the 'Alert FoV 90', so that the succubi would not spot me. Not sure whether this also blocked the exit. On the other hand, once I had started the raid (with the unmodified json file), I could also not leave the room through the exit (in that case, without having helped the girl since ...too slow...).
