The highlight on the character "Mark" does not work here, but in all other dialogues with him it works. I tried changing the names of the files, as they only have differences in names, but it didn't help.
Right now I was thinking that it doesn't work because of the previous replica of this character. In front of her I have a sprite in the middle with two characters pushing each other and Mark is talking at this time. After that, the sprite of the two characters is removed and Mark speaks again. It is at this moment that highlight does not work on the character Mark.
It is here that the backlight and its animation on the character Mark do not work:
