Hello,
Am I allowed to:
1) Roll a safe even if all revealed tiles have a green token on them?
2) Check the top patrol or event stack that I already know to waste an action? Same question for the patrol card that I have seen 10 turns ago.
3) Move one away, check the patrol or event stack, and then goes back to my orginal tile with that new information gained? Is it the same if I'm always going back whatever the top card will be? Should I instead always check that card during my first action since there is no point of checking it after my first action except trying to waste move after that? Is it the same if I already know that top card?
4) With juicer advanced, use two actions to not trigger a laser and immediately after create an alarm in that laser tile?
5) Move the bird to a three away tile (and come back) for no reason except wasting 4 actions?
6) With normal juicer, create alarms in a lot of places to make the guard do the same thing every turn ; even if yourself you are not doing anything useful.
7) With advanced hawk can you move once, use your power in a one away tile and move back to your starting position (same than 2)
8) With advanced hacker on a fingerprint room, can you move away, come back and trigger that fingerprint but use your hack token, and then use your ability?
9) What if you just dont use your ability? You spend two actions to lose your hack token.

Thanks

Let me try to answer my own questions:
1) this look like a really minor bug, so i suppose that shouldn't be allowed? so no
2) that one is annoying to deal with. I could said I don't have a good memory and need to remember what I checked earlier. One game out of 100, that happen for real. But at the same time, you know what you are getting. I suppose though that should be legal since we could be in that 1 out of 100? So yes?
3) huh I guess yes. Even if I know I'm going back to my tile, you can't know when i look at the top tile if I'm doing something else or not.
4) that one look cheating? So no? I could see both ways working.
5) yes? That change things on the map.
6) yes
