Hi, I encountered a crash when attacking the Spider Queen with Shattered Spiders as followers.The crash happens right after the shattered spiders attack the queen.
My first guess was that the queen got one-shot and some value that prevents the spiders from attacking her further was not available anymore, but it happens with as little as 7 shattered spiders and the damage is not high enough to one-shot her.

EDIT: Edited title and description to better reflect the issue - Also only shattered spiders trigger it.

It occurs with this as the only active mod, so here is the relevant part from the log:
