When playing today, at one point during the final fight in Skittergate, Rasknitt and Deathrattler both stopped fighting completely, allowing us to wail on them and snipe them to death. It came up when the last man standing (Ranger Vet) went invisible to rescue the rest of us. The enemies present reacted as usual when a lone character goes invisible, just standing around without fighting, but once the invisibility ended (and the rest of us got up to continue fighting), they didn’t return to their normal AI, instead continuing to stand there even when they were attacked. Additional enemies spawning afterwards fought normally, and Rasknitt and Deathrattler both died normally too. The two were separated at the time this happened.

I can probably get the log from the host too, if that helps more.
