Setup:
Night 1 (Replay timestamp ~3:10)
Player Role Action
4 Deceiver Hide behind 6
5 Coroner None
6 Bus Driver Swap 4 and 5
9 Mass Murderer Spree at 6's house

Result:
Both 4(Deceiver) and 5(Coroner) are killed from Mass Murderer spree. Bus driver is not.

Bug?
5, the Coroner, should not have been killed by the Mass Murderer. It seems that when the Bus Driver swapped the position of 4 and 5, that caused 5 to "visit" 4. That "visit" was then redirected with the Deceiver's ability to go to 6's house. Since 5 stayed home, it should be expected that his inaction wouldn't result in him "visiting" 6's house.
