I found that when I have a node with "SetActive(Subtitle Panel 1, false)", the portraits in the following dialogues using the same panel doesn't show up anymore. Not even if I include in the next node SetActive(Subtitle Panel 1, true)
The weird thing is that in the Hierarchy I can see how the object panel is disabled and enable once the character talks again, but his portrait is not displayed. No idea why this happens.
Edit: The workaround is using SendMessage(Close,, Subtitle Panel 1) instead. Anyway, I think it might be worthy to take a look when you have time.
