Hi, just wanted to let you know that GOG has a broken download link to Symbiant adult patch and they have been unwilling to fix it for about two weeks now. So if someone buys the game over there and wants the patch they won't be able to get it.

Greetings, we are sad that you had to comment on itchio in order to reach out to us. We tried updating the build through GOG's tools but it's still stuck in the oldest available version. We reported the issue to them and they'll probably get back to us next week.
In the meantime, the adult patch on this page should work if you haven't tried that yet.
