Yes, it's clearly a bug that has to be fixed.You are right. Wow.
Don't you think it's affecting gameplay (for example planning the expansion) if you can't see a really long river on the max zoom in?
Are we supposed to go back and forth between views just to see where all the rivers are?
Otherwise, I love the new game and what they've done with it, apart from a few technical issues which I hope will be resolved in patches.
Thanks for clearing this out for me.
Because there is a river that you don't see in this mode.
Switch to strategic view and you'll see a river going to the northwest of Thebes. (the corridor of provinces getting 1 gold)
