I was told by another player that when the unit is grey and it shows 0 that your spy didn't get info on that unit. I called him out on it but he still don't believe me. Any opinions on this subject from veteran players?
If a spy is successful it will have a Green Flag.
If a spy fails it will most likely be grayed out. (Not sure on this..)
If a spy report says it's got blood it means you've lost spies but not all of them.
If a spy report says it's got blood and you've lost no spies you killed one of their spies in their villages.
If a spy report fails completely with a skull symbol it means your spies have died.
I'm talking about the actual report, he is telling me if the unit is grey and 0 that the spy didn't get info on that unit and there may be some there. I told him support most likely landed after spy report.
I concur with DC. If the report is green, then you have the correct units no matter if it says 0. If it says 0, then there really are no units of that type in the village or away from the village. If the report is red (blood), then it will never show you what is away from the village (always will show 0) and some countermeasure MAY have been activated on the units that it shows are in the village (red is not a guarantee that a countermeasure was activated).
