ok i finished the story twice and i can't find tc after i finished the story but she still message me that she needs a bunny even when she already got that before she disappear. The beg skill don't work in free mode and i can't unlock it in story mode and my fapet after being corrupted when i order them to rape after one time only their stamina drop to 0. I don't wanna mention how many bugs are in the game... is still enjoyable but it really pisses you of with this huge amount of problems.
EDIT: ok for the beg skill you need to be crouched-locked but is not explained in the tutorial. It say only to use the caps-lock button and press 1.
after the End of the Chapter 1 of the Story Mode, TC will go missing because she will go to a unknown place, so you will not find her anymore till Chap 2.
The thing with TC asking for a bunny maybe is related to the "Crossdresing Missions" which will ask you to bring a fapet to TC so she can do s new dress for you.
Since you discovered how the Beg skill works, I'll just say that the "Crouch Lock" and the right use of the controls and skills is mentioned in the Book>Help>Basic controls / Book>Fapetstiary>Skills and if you go to the Esc>Options menu you will find a a option to crouch the character by pressing C once, instead of the normal way.
By Corrupted Fapets I'll asume you are talking about Broken Fapets, those kind of fapets are sex addicts so they will starts a non-stop sex until they get 0 Stamina.
Or in case, there is a gimmick in this game that makes a Low LVL being lose much more stamina if is fucked by a being with More Levels than they
