Telika: I have a tentative evidence that keeps insta-reappearing when its timer goes down. It also insta-reappears after a follower is jailed. I suspect a bug, is it a known one or have I missed an explanation ?

I'm facing a weary detective with the "idealist" trait. No "erratic" sign (which would explain evidence re-popping out of nowhere). Is that trait hidden ?

Spellsweaver: If you produce no notoriety then it's indeed a bug. Does it just reappear by itself, without going through any timers?
As for reappearing after follower being jailed, it's the way it's supposed to be, damning evidence turns into a tenative one when it happens.
