I don't think this is anywhere in the rules, but it seams kinda logical to me, so:

1. If you start a fire (put a fire token) in the room with darkness, do you remove the darkness token from the room ??? I don't think it says anything about that in the rules, but it seams kinda logical to me ... I mean fire=light=no darkness ...

2. If you want to perform a non-attack action with an investigator who is in the space with a STUNNED monster, do you have to make an evade roll to do so ??? Again, logic ... If the monster is stunned, it says it can't move or attack, so I guess that means it's knocked out, on the floor, or whatever, so why would you need to make the test ???

I looked through the rules again, and nothing about this is in there, but what do you guys think ???

Gah, never mind ... Just found both answers in the errata =/

Q: Can both fire and darkness exist in the same room?
A: Yes. Thematically this darkness is actually thick black smoke.

Q: Do stunned monsters cause evade checks? What about horror checks? Can they take samples?
A: Investigators can freely evade stunned monsters (because they cannot attack). Stunned monsters still cause Horror checks and can still take samples (although they are not moved after taking the sample).
