I found a display bug where a broken trade route is still shown on the map to exist. In the attached zipped save file, Trade Routes 0737_AD-1684.zip, a worker right to the West of Utrecht is removing jungle (to prepare for building a mine on the aluminum). I'm getting 165 gold/turn from trade routes. The jungle tile creates a trade route due to the Iroquois UA (The Great Warpath). In the next save file, No Trade Routes 0738_AD-1686.zip, the jungle has been removed and the worker is now building a mine. Two popup messages to the right of the screen state that the trade routes between Utrecht, Amsterdam and my capital have been broken. My gold from trade routes has decreased to 137/turn.
All of that is in order. However, the map still shows that tile as having a trade route. The attached screenshot shows the map in strategic view with the trade route overlay enabled. The tile to the left of Utrecht is still yellow (indicating a trade route) and the mouseover popup message also shows that a trade route still exists. I played the game for several turns and the map continued to claim that a trade route existed. This display bug is annoying because it made it difficult for me to track down the cause of the trade routes being broken. I searched the forum, but couldn't find this bug being reported before.
