Weird message
I get this all the time. I also noticed this if there’s a huge amount of lag between initiating the conversation with the NPC and during the interaction. I get the next dialogue after this box shows up. I think it’s also because the conversation content is still being loaded and we are greeted with this placeholder.
Maybe a delay between each dialogue box is needed, but until the lag is solved, it would cause a very noticeable delay between each line of dialogue.
