This is bad. I have a rough idea how to solve it, but without knowing how to reproduce it, I can't promise the fix will actually work. I'll do my best though.

If I had any plausible hint at how to reproduce it, I would have given it, but the crash caught me off-guard, I didn't paid attention to what I did...
I posted this here "just in case" in the end, a stacktrace can be helpful to at least reduce the scope.

[Varkalandar]

The stack trace sure helped. A possible reason is a new creature arriving just while the party selector iterated the creature list. There is a suggested pattern to prevent this, iterate on a copy of the list. I've applied this pattern now, so with some luck, this crash should not happen in v0.26 anymore.

I hope I could fix this in v0.26 but since I could not reproduce it, I had no way to test if the fix actually works. I'll keep this issue open and see if more reports come in.
