I have experienced this bug in my recent Scicilian campaign as the Greeks, it has not been a major problem, but it was annoying when my cavalry charged through a port, the walls not the open space. It is a bit of an annoyance, but not the top of my bugs list.
You do have a bad attitude, if youi listened to people and treated them respectfully you would get much further, you should also look beyond someones views on bugs and not judge them on this one issue.
