The fact you've had investigations tells me Carbuncle hasn't protected/roleblocked you every night. Your role was outed on day 1 - even if you didn't confirm or deny it, the Cult would have known and made you their number one target.
I don't see why power roles would be immune. I think you were converted. If not the first night, then some night after that.
There's also the matter of your "investigations". Doomtrain turned up Insane, yet the Dud is believed to be a variant of the Bomb, which is town-aligned. Town-aligned means Sane apparently.
This was posted when the vote count looked like this:
More and more suspicion was being thrown towards Siren. I had also voted for Siren earlier because she was the most suspicious (until Anima good lord). It was quite possible that Siren would be up on the chopping block that day.
Also Bahamut (who I believe is a confirmed town, as his role did exactly as he said it would) said this the same post as his vote count:
I am almost certain you're a Cultist, Titan. However, I'm not looking for any ordinary Cultist. I'm looking for the leader, and you revealed your "investigation" to save Siren. I think Siren is the Cult Leader and I think you need to die.
##Vote: [M] Siren
