i was masoned n1 and masoned somebody n2, but killed by the mafia that night. when i died, i showed up as my original role. what's up with that?

i was guiser. we killed someone and i guised as them. the person i guised as had visited thulu the night before and so did my partner. except my partner was actually thulu'd (couldn't vote or speak properly) but i was...half thulu'd? i had the do not vote but i could speak fine. so people assumed i was tree. but then the game expected me to vote or something and i "vegged." it was...weird.
