1. I have the situation where one of my heavy cav unit is behind a hill on ground with high 0. the hill is wide, so no enemy could see me. next field is 50 and the next is 100. when I move my cav to high 50, I expect not to be seen by other player, because the high 100 field is in front. But my LOS changes on this field, so that I can see the complete area in front of the hill. That is unexpected. Also I'm afraid the other player also can see my unit too.
2. Sometimes I see in the replay moves from other players, which were taken back. I saw for instance a unit of light bow men coming out of the woods and teleports back. That is not a good behavior in the replay, because as a result you can see possible traps.
3. Similary to point 2, I think it is not so good, when in the replay moves of hidden armies are hearable in sound parts. So you could calculate the amount of units behind a hill or in the woods. Maybe this behavior is also wished from your side. But in reality I don't think that you can hear units behind a hill so clearly, when you r on a battlefield. Of course this could be acceptable behavior to hear the units particularly, especially when you hear the units in the woods.

Btw. I really like the game.
EDIT: @support btw2 I have a game "The Standard (Anglo-Norman vs Scots) which I can't send to the server. Maybe you want to have a look for debugging to find the reason.
