So I have a bug where a hostile Mr. Gutsy, protectron, or Robobrain will spawn were neutral robots are. I have the increased spawn mod, which I believe is totally responsible for the bug, not TTW.
I was doing Tranquility Lane last night and a few seconds after exiting the house with the Mr. Handy, all of sudden I hear, "You have insulted my honor, and for that you must die!" moments before being disintegrated by a plasma bolt.
Turns out a hostile Mr. Gutsy spawned in tranquility lane and ambushed me. But it was one of the more funny random moments in all of my Fallout experience :)
P.S. I had some trouble getting Tranquility Lane to work. It loaded fine, but there was nothing but a black screen when I arrived. I suspected it was due to NevadaSkies, and it worked perfectly after I disabled it. In case anyone else has that problem.
