I want to say something about traps becpuse those things are… lets say broken(not in the OP sense). Allow me to elaborate. Traps are supposed to be balanced, as well as they are an information battle, where logic and intuition are 2 of your 3 weapons to find out where is a trap and what to do to avoid it(lets supose you dont have those anti-trap units). Witch is the 3rd weapon? Well:
Lets say, imagine i have lila (:3) in here, what should i do? Well, i have control over 2 panic squares, so obviusly put a trap in one of them. But 2??? That seems as an uneficient number for me… 
.So, i will just, move lila to the square next to my hearth, and now, i have control over the other panic square too!(I could place a trap in one of the first panic squares and then move).And now introducing the Scrhödingers Trap! In all 3 panic squares, there is a trap, and at the same time there are not!. Its not until you place an unit that the reality colapses and you get trapped… or dont!. And even, there is the posibility of that no traps were placed, and i saved it for next turn to place it better!
Well, at least that is what happens in arena battles, but in asyncrone… there is one thing, the secret weapon…
Just kidding, there is nothing! AND THATS EXACTLY THE PROBLEM.
In the replay, there is a time in witch “nothing” happens, no phobies moving, no atacks happening. Well, i will tell you, thats the trap being placed!. So far i know, you cannot know where it is placed, but you know WHEN it was placed, ans in our scenario:
1: lila does nothing and then move: trap in panic square 1 or 2
2: lila moves and then nothing: trap in panic square 2 or 3
3: lila does not do nothing: no traps have been placed
Yes, i have won so many battles like this, and i dont remember who and that replay is lost, but somebody even took out popcorn and placed a trap rigth in front of the imaginary just to '“counter” that time lapse, making me imposible to know when it was placed the frost trap.
For an advanced doomsday III player do this, it means this is something serius. And that single fact makes arena diferent than asyncrone, as in arena you can wait whenever you want and there is no way to tell(so far i know).
I place is as a bug report becouse i know that you should not be suposed to know that, and if you were, at least the “trap hability” from the enemy would show that it haves the cooldown active.
Thanks for reading :3
