So i did the questline for the black eels. i pick to attack from the old junkyard with the sgs guys. As soon as the fight starts roman dies of nothing. He doesn't get hit (at least the logs don't show any dmg that i can see). He rolls initiative and dies.
Edited to add there is also some slowdown in the fight at least the start. The other guards take too long to move/act. Not sure what is going on exactly.
