Multiplayer Help
Co-op issues in this game are usually connection-level rather than save corruption. Work through these in order; the early steps resolve most reports.
Try these in order
- 1Confirm you are both on the same buildA version mismatch is the most common cause of a join that fails immediately. Let Steam finish updating on both machines and restart the game.
- 2Have the host restart the lobbyIf joining drops you back to the main menu, the existing lobby session is usually stale. The host should return to the menu and create a fresh lobby.
- 3Verify game filesUse Steam’s file verification on both machines. A partial update on either side can break the session handshake.
- 4Check the network pathRestart the router, disable VPNs, and try without any network filtering. Connection-quality problems tend to show up as reconnect loops rather than clean errors.
- 5Rejoin instead of reconnecting mid-dayIf a player drops during a casino day, having them rejoin from the lobby is more reliable than repeatedly attempting to reconnect.
Still broken?
Multiplayer fixes have shipped in several updates, so report a reproducible case with your build number rather than working around it. Check the update notes first in case your issue is already fixed.
