Having a bit of a problem with the first Turles battle, the game always crashes right as the end cutscene starts (the one where the XV1 character shows up).
I tried it on a different character that previously completed the mission, but that one also get the same crash as soon as the cutscene starts. That same character can view the cutscene replay without issue, though.
I found a Steam thread where someone mentioned the same crash due to mods not being up-to-date, though I can't find any of my installed mods that need updating. I checked for mods that have been updated recently, most of them haven't even been updated for at least 3-5 months and the mission worked fine more recently than that.
