Description
Errors appear when starting, stopping, and then starting again the host when using multipass. This happens when enabling predicted spawning.
The errors are logged:
Object Id[x] already exists within ObjectId Cache

X number of times for however many reserved objects Ids I've set in the ServerManager setting.

Replication

1. Import example
2. Run in editor
3. Press button to start connection
4. Press button to stop connection
5. Press button to start connection
6. See error

Expected behavior
No Errors

Do we know if this is still an issue on 4.6.12?

[maxkratt]

Just tried again on 4.6.12, it's still occurring.

[AranyhalStudio]

Any ETA on when this will be fixed, it's happening to me too and it's unsatisfactory

[FirstGearGames]

The error is harmless. It will likely be resolved the next release.

Resolved in 4.6.13.

Open ClientManager.cs

Find method: private void ParseAuthenticated(PooledReader reader)

Find lines

                for (int i = 0; i < count; i++)
                        q.Enqueue(reader.ReadNetworkObjectId());

Replace with this

                for (int i = 0; i < count; i++)
                {
                    /* If host then just read Ids, but do not
                     * enqueue as server side already did so. */
                    int id = reader.ReadNetworkObjectId();
                    if (!isServerStarted)
                        q.Enqueue(id);
                }

Note: the fix above has been updated to be correct. Previously it was not parsing data correctly.

Those on 4.6.13 - 14 may have silent spawning issues.

Fixed in 4,6,15,
