And how would he release this patch unofficially, e.g. here?
He wouldn't. He doesn't release anything here. He only releases on Patreon. Subscribers leak the Patreon-only downloads here.
Someone would need to code a mod and manipulate existed artwork or draw new artwork in similar style and write a script that sits completely separate from the Unity edition Uberpie creates. Then that person could upload the mod somewhere for download. Both the game and the mod are then downloaded by one user and put together per mod instructions (it can't just be content already in the assets of the game that get "unlocked" - that also violates Patreon TOU).
If he were to do it even secretly and someone ratted him out for some reason, that would put his income in jeopardy.
So anytime one of the animations is supposed to play during sex scenes it just shows a black screen instead. Dialogue proceeds normally and the still image CGs come up after the animations finish (or even mid animation if applicable) but the animations themselves are just not loading for whatever reason.
In fact I had assumed it was just placeholder until I saw the video walkthrough for the latest update and noticed they had the animations. Any idea what is wrong?
Things for you to consider - the age of your computer, is your OS up to date, are all drivers up to date (video, audio, etc), do you have sufficient RAM, do you have similar problems with other Unity games, are you running several things at once.
I was talking about the Whole NTR route Vs The Whole Alpha route, I think individual updates will be released at similar intervals but the amount of story covered in each update should be drastically greater, IF they are reusing the same scene as I suspect they will
(and obviously not counting stuff like animation upgrades).
Ah, my mistake in understanding your message. My apologies. The person you were replying to was asking about when to expect just some NTR content and you are speaking about the whole NTR route. My response would have been better for him - February to April, optimistically, for the next update that is planned to focus on the initial development of the NTR route.
Yeah, in comparison, it should take less time to develop the entire NTR route as well as the entire Friendship third route than it is taking to do the Main route. Though - you and I have patience for whatever it would take - others shouldn't expect a miracle. It's been over four years on the main route, and it's not done yet. It could easily take over a year, each, for the other two routes.
