Got a consistent crash as the Huntsmarshal's Expedition in Vortex Campaign, where if I try to Raid a Vampire Coast territory to advance the special Witch Hunter's quest chain thing the game always crashes when my next turn is trying to start. Originally this was happening back in the update that broke Weapon Strength modification mechanics, as well as in the beta patch that fixed that issue, but as of the current patch I started exactly such a run again and it's still happening at the exact same point.

Delaying a turn or three before doing the Raiding to see if it's clashing with some other event doesn't help. Looking up online indicated other people have gotten Huntsmarshal's crashes that can be bypassed by setting the camera to ignore everybody else for the turn, but trying that didn't help. Trying to Raid different Provinces hasn't helped. Having this mod installed or not doesn't affect it. No matter what I've tried, Raiding a Vampire Coast territory results in the game freezing and crashing once the final other faction turn ends.

Notably, starting the Raiding immediately triggers an announcement that I've encountered the Defenders of the Great Plan. My best guess is the quest chain assumes they already exist and Nakai hasn't gotten around to conquering any cities just yet, breaking the event, but I really don't know why it's happening.
