Found it. I guess the role for accepting the rules hadn't synced yet, I didn't see any threads in the channel younger than a month. Restarted discord and found the thread.
So as a summary for all those who don't want to use Discord (I'm leaving the server immediately after as well): Setting the Honeycomb Bravo selector switch for the autopilot variables to IAS causes this issue, so as a workaround one can select a different position and not use the selector until it's fixed.
