I think it may be she just despawns inmediately because I can see her sprites while you're talking but the second the dialogue ends she dissapears. The health bar does appear, though.
I'm having the same issue 😭 both the witch and necron. I know it's been three years since the last update but this game is a lot of fun and I want to finish it
Since it has been a long time since the last update I uploaded, I don't remember off the top of my head if I found the fix or not since then. I assume so, as my testers haven't had any issues getting past that point. The full version of the game will be coming out in October though!
