So where do we find the documentation that covers the change "Fog of War Implementation (Update/Change Visibility Rules)"
This is a highly disruptive change that has not been pre-announced and I can find no documentation for and all the players I talk to don't understand
There's a separate discussion being had about whether the change should be reversed, but I am purely asking about given the change has been made where can we see details to understand expected behaviour
Or is this just a ploy to get HC for Bugs being raised only for the response to be "That's intended behaviour we just didn't tell you"?

really....what's up with this fog....at least some plausible explanations

This game has suddenly become rubbish!
