Current v1.009 context
The v1.009 multiplayer fixes cover further synchronization cases. The earlier fixes and diagnostic checks below remain version-specific; do not treat them as guaranteed connection repairs.
Quick answer
Confirm that everyone is on the same version, rebuild the room, try the official Steam invitation or room-code route, save the exact error, and exchange the host for comparison. These are diagnostic checks gathered from the reviewed material; none is guaranteed to fix every connection problem.
Diagnostic checks
- Compare the exact game version on every participating PC.
- Recreate the room and test again.
- Try the available Steam invitation or room-code route.
- Capture the complete error rather than paraphrasing it.
- Exchange the host and compare the result.
Community-derived checks: these help separate version, room, and host conditions. They are not official guarantees.
What v1.008 records as fixed
- Guest players can use Pizza Station ingredient capacity added by Pizza Chef levels instead of being limited to 20 ingredients.
- Pizzas placed on shelves now appear on the shelves for guest players rather than on the floor.
- When a guest removes a pizza from the oven with a tray, cooking now stops on that guest's screen.
These are capacity, shelf display, and oven synchronization fixes. They are not a general connection fix.
Possible remaining problems
The v1.008 source does not list a universal fix for room creation, invitations, disconnects, or every device desynchronization. Treat those as unresolved until the exact symptom and version are documented.
Historical Demo note
Demo updates once addressed a “session found but can't join” case and join-by-code behavior. That history does not prove the formal release currently fails for the same reason.
