Yeah, when I first read that I didn't think anything about it because I read it as "I don't know his City Role". But now that Salvage pointed it out and I re-read it, it does seem suspicious.
Mafia is certainly possible, another possibility would be a role he didn't want to claim to avoid being targeted. Likeliest being Cop, but with claimed Tracker and (weaker version of) Voyeur, that would be a ton of intel - as Backfire pointed out already - so it doesn't look too probable. But then there is Rantai's Miller claim which suggests the existance of a Cop. Either Rantai is fakeclaiming (which would mean he's scum), town has massive intel, Backfire is a Mafia Tracker, or Rantai's role was added to confuse us.
I currently doubt it's the last one, the game is already confusing enough and further meddling would probably just hinder the game flow.
That makes my top suspects Lilac (from what happened so far), Rantai (Miller claim) and KRZY/pieguy (for obvious reasons).
I don't really trust Backfire yet but his role has a possibility of being confirmable depending on night happenings and even if he is a Mafia Tracker we could likely still use his information to either aid town or expose him as scum.
Salvage seemed reasonable in this game, he is scumhunting (pointing out the quote for example), so I'm not too suspicious of him right now. But i also know how impossible it is to get valid reads on him and we all have two roles and possible alignments, so asdfg w/e
bmin scummier than Salvage for lurking and stuff but I have more concrete suspicions for the people listed above.
How to handle the KRZY/pieguy incident? If we assume that he is either Mafia or Cop, we could encourage a Cop claim and catch a Mafia (Either him or the counterclaim). But if his double-Vanilla claim was true (unlikely imo) we'd just expose a possible Cop. At least the existance of a Cop would make Rantai's claim more believable?
Or we could lynch him, if he doesn't flip Cop and the next day nobody claims Cop either, we could lynch Rantai?
I don't really like any of these options,so feel free to suggest different tactics.
Meh, this is complicated...
