Previously, when I had campaign and characters in it - PCs occurred in characters select. Now I can select only party and select of characters is empty. The characters, even when in party, do not appear in select. The characters also dont appear in the preview of card.
Fix this issue or revent how it was previously, or add some explanation why the characters are not visible.
I think I see where you're coming from with this! I have a similar issue with some of my articles: I cannot reference Player Characters when using drop down boxes.
Still working as usual on my worlds. Perhaps should you log it as a bug and give more specific information.
