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, and make sure everyone is on the same build.
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.
