Suggestions for tonight:
If FLEX is NOT LO/Forger/Jugg/Witch, Hatter is lying and Jailor/Vigi can take care of him (unless there's Transporter shenanigans in play, which doesn't seem to be the case, and there's no Disguiser per Spy results).
Invests, check Jericho, if he comes up Sheriff/WW/Exe/Poisoner then he is basically confirmed assuming Devise is legit.
Trackers, check Psychic claims. If they go anywhere obviously they aren't Psychic.
Spies, bug someone you think might get "roleblocked" if you know what I mean.
Sheriffs, check someone who hasn't claimed yet. 4 times out of 5 the people who are last to claim are evil.
TP, protect Mayor or confirmed TIs.
