I'm wondering now if it was the Mimic that screwed me over on the first out? Like if I'd forgot to clear that one and too close to that room, not sure there.
I reloaded a save from the Durge run at the Shadowprison scene to about-face on earlier trajectory. Only had a brief hiccup there... lol
The urge said to kill Lae'zel, but we were having absolutely none of that! hehe
Did the whole thing again just now like I remembered doing the first time, but this time around I guess it worked as normal. I've fought that fight a bunch of times now with just 3 thinking it was necessary to get her early hehe. Learn something new all the time I guess!
