It's not quite a bug, but when you give two HJ to the centaur while you have the catamite and chose that instead of fighting the centaur or leaving, you still get a message saying you have cum in your ass or stomach. I mean, shouldn't it state that you got a facial or something?
And maybe it's on purpose, but in one of my plays I got stuck, because I was too far away from the town and had too little food to reach it before passing out from hunger and being ravaged by beasts which leads to a game over. I guess it would be nice to have the dryads "quests" (I don't know what to call them) not disappear after visiting them once. I will update this post if I find another thing.
