No worries! Thank you for letting me know about the expired link I will get to fixing that when I have a moment. As stated in the itch devlog the next update is expected for late March, early April. It will most likely be some time next week on any day other than April 1st.
edit: As far as I am aware the discord link works correctly! It is an 18+ NSFW server and I was informed apple users may have trouble getting in as a result. The only other advice I can give is that the link is case-sensitive if you're manually keying it in.
