I have absolutely no idea what caused it, but none of my scripts reference the service.
Is there a certain requirement that the character must have in order to show the bubblechat?
Create a blank template project and enable that property and then type a message in chat, a bubble will appear over your character’s head. You must have some script(s) and/or plugin(s) which are setting this property back to false during runtime.
Bubble chats do appear above my character’s head. However, for each player, the bubble chat is local sided. Classic chat will show globally, but bubble chat will not show for other players in the game.
Try setting archivable to disabled, I’ve had issues with archivable things not showing up in the game and setting it to false usually fixed them not 100% sure that this will work but give it a try
