Multiplayer signs break on load for clients

Upon loading a Changed Wall Sign, clients break with
INDEXARRAYOUTOFBOUNDSEXCEPTION ARRAY INDEX 5 OUT OF 3
And I just thought through the error and I've come to some realizations.
You might be declaring these signs as SIGN ENTITIES, which breaks the handler for signs in vanilla.
It's not getting the messages field which is what breaks the handler.
You can instantiate a workaround fix by providing dummy fields which are empty, this would stop the crashes.
However, a complete fix would be overhauling the wall signs to instantiate them as PAINTING entities.
The client does NOT expect text to accompany these.

Non vengono indicati file, test o punti di ingresso. Inizia tracciando come vengono istanziati e gestiti i Changed Wall Signs al caricamento del client, quindi confronta il percorso dell’entità insegna con l’approccio suggerito dell’entità dipinto; il lavoro è completato quando i client multiplayer caricano queste insegne senza l’eccezione di limiti dell’array segnalata.
