Am guessing this is perhaps not so much a bug per se, but lack of support in relevant scenes, but nevertheless -- having a cockvine doesn't enable following post-victory options:
Bothrioc Pidemme -> "Dock Ovi"
Queen Taivra -> "Breed Her"
the latter in particular is a real sadface, as the player otherwise can perform docking with other (alpha/beta) nyrea using their tailcock, and the queen herself does exactly that with dozen of her subjects at once. So the tooltip explaining why you can't do the same makes little sense in this context
