Hello,
Sorry but there's no wiki (at least none of which i'm aware of), mostly just forums, however everything is supposedly documented within game: Book (Fapestiary, Help Section) and Visual tips (Esc > Option > Help > (left-right)).
"petting for example" : strange, it should've appeared in Visual Tips and in the Book (all learned knowledge appears there along with the corresponding notifications). Was it in Free Mode or Story Mode ? Was it a older save (from before the game release), a continued save from demo or a new save ? If the issue persists i could check the save.
"manual save" : the only way to safely save is by using sleep (via quick commands or interacting with a bed). This was considered for preventing quick saves and lots of reloads. Currently the game is based on day pass type save, since lots of things are randomly generated and calculated at the start of a day. In other words, i could try yet there's a high chance it would end up being very buggy, sorry.
