I just had a weird game as witch.
I controlled the veteran n1, sent vigi into them n2, killing the vigi, and then I sent the spy into the vet, killing the spy. The strange part is that when I controlled the spy, it said his target was transported (which was true, since the trans also died to vet that night). Now, I know I forced the spy to visit the vet. But if the vet was being transported, shouldn't the spy have visited whoever was being transported with the vet? There was no leaver that night, so the visit couldn't have failed (and even if it had, I think the vet wouldn't have received the transported notification).
The spy left as soon as he was killed (right at the beggining of the day), so the game said "he was killed by a veteran and also commited suicide". How is it possible that he died? There was no hypnotist (RM were 2 forgers) and the trans didn't have an updated will.
Also, if what the game said was true, then that means I controlled 2 townies into the alerting vet, killing them. I should have gotten the "double edged sword" achievement, but I didn't.
Here are some screenshots. I also recorded the whole game.
