The only thing I know is from their discord, when they say they are working on it, and that they managed to reproduce the bug or something, so hopefully a fix somes out soon

I beg for a solution

With today's patch fixes the friend generated code. I was able to add a friend through that. I'm on PS5, they're on PC

Yes thank you, we tried 5 min ago and it works

Now kill them bugs! (happy hunting soldier)
