Meccha Chameleon Can't Join Fix

When a friend cannot join, the fix is usually room state, version state, or invite state.

Quick answer

Create a fresh room, send a fresh invite, confirm every player is online in Steam, and make sure everyone is on the same build. 中文：重开房、重发邀请、统一版本，别先乱装补丁。

Join-failure flow

Have the host recreate the room with default settings. Then invite one friend first. If that works, add the rest of the group; if it fails, the issue is not the old room.

If only one player fails, check their Steam status, overlay state, network restrictions, and whether they are launching the same app build.

Host creates a new private room.
Everyone restarts Steam and the game.
Host sends a fresh invite after the room exists.
Test one friend before inviting the whole group.

FAQ

Why do old invites stop working?

Room state can change after a host restarts, changes settings, or recreates the lobby.

Should the host or guest restart first?

The host should recreate the room first; the failing guest should restart if the fresh invite still fails.

Can a version mismatch block joining?

Yes. Every player should update through Steam before retesting.
