He took a safe fake that was a vengeful townie, for whatever reason decided to change how it works and added a second step to it.
Instead of killing someone when I was lynched, he had me claim that when the town bodyguard was killed, I received a vig shot.
So I claimed vengeful townie, despite it never working that way, ever. So here he claims lie detector that can only be used at night, not commonly how the role works, and he gets a refund if he confirms a townie? Why? That makes no sense.
Without a cop you have to assume town only has one chance to catch a scum with an alignment role and one chance to kill scum with desperado? Or three shots to confirm townies, and no shots to catch scum? Seems like a really weird balance to me, but IDK.
My guess is lie detector is easily fake-able and can become poe so why not get a second chance to "catch" scum.
