the last one i am missing myself
EDIT: still searching - for half an hour now - if this game will continue to be such a stupid puzzle game, i rather go xhamster and watch some real porn.
This is again another good example why people tend to dislike sandbox games. Some developers think it's funny to do "puzzle mini games". I mean: "Who the hell puts used cloths in the kitchen on top of the waste-bin? the quest tells "COLLECT the cloths" and NOT "Search hours for the last place an obviously drunken sadistic developer put them in place" XD
