This is a configuration error. We're working on finding and fixing such issues. If you let us know where it occurred, we'll fix it.
Yes, I would be happy to tell you WHERE this is happening, but this is too COMMON, even from the version when there was no card battle! Then the character will say my character's line, then on the turn or even speaks, but the color of the text is as if he is performing an action, and there is no name of who is saying it. It doesn't directly interfere with the game, but it still catches your eye!
