UCIK is in beta. Report issues on Discord and they go into the next release.

Next release

EOS lobby members publish their login name, so Discord players show their Discord name instead of username#0.

24 September 2026

Use Presence on Crossplay lobbies and sessions. EOS overlay parties and friends join from presence, and the overlay shows one party.
EOS sessions show the full party in the overlay, with member names and the host.
Kick Crossplay Player From Server notifies the kicked client, which leaves the game instead of starting a host migration.
Joining and traveling to a session you already hold now just travels, instead of failing with already_in_session.
Host migration elects only current members, waits for the world when elected during a map load, and restores late joiners more reliably.
A game you leave stops being advertised in EOS presence.
Positional Discord voice applies the Discord output volume to routed speakers.
