I got tired of adding new threads every time I ran into an issue.
So here are two small problems for the price of one.
Firstly:
Is it possible to check, from a dialog, if a character is dead, or would we need to set an appropriate flag in the Story editor?

Secondly:
If something should affect everyone in the same party as a specific character (i.e. everyone linked to them with the little chain thing), is there a way of looping over those people in the Story editor?
