The only real points of contention are Ken vs Mitsuru as Cop, and Shinjiro vs Elizabeth as the Vanilla Town (from my point of view since I'm Vanilla town).

Mitsuru I'm aware that the host can make up their own stipulation regarding a role, however the condition you're describing isn't the way the sanity mechanic works with the Cop role. So forgive me for doubting your claim. I'm not going to deny that it could potentially exist, I'm just saying it seems very weird to me and maybe even a little suspicious.

I also find the fact that Koromaru came out and claimed Doctor within 15 minutes of your reveal as Cop kind of suspect. His claim just so happened to validate your investigations while simultaneously clearing himself. Either he was caught by the Cop and tried to take advantage of their investigation mechanic, or you were both in on it. I think the former is more likely to be the case.

The problem that we have now is that there's two false claims to check. Aigis will almost certainly be killed. The only confirmed role we have is Junpei as the Tracker. Aigis could opt to protect Junpei although I'm unsure if it prevents roleblocks. I've been trying to think of solutions as to how we could out a mafia with his ability, but every single possibility is full of holes. At this point it basically looks as though Junpei's ability is nearly useless.
