in fact no animations are needed but thats another conversation
but.. knowing you are going to do animations since you started the game in 2017
knowing your script because it was written in 2017
knowing that you'll have a sex scene in this update for years now
and then instead of preparing months before you leave it until the end so you can charge an extra 2 months on what was supposed to be the quickest update since ever..
something doesn't sound right
Knowing he will have sex scenes and knowing which sex scene will be animated are different things.
He had done sex scenes with Liam too, he didn't include animations for that.
This is the 2nd part of the game starting, since it's a new part he most likely wants to add what he has been wanting to add.
Also I don't understand this ( not directed at you ), people say he should have done this in the background. But wouldn't it have still taken time. Finding, organization, learning. All of this will still take time. So whenever he was going to add these things that update would have taken long. There is no way around it.
