Missing items on campaign map

I posted this in the Entrance Hall a while back. I hope it is ok that I post it here. I thought maybe more could see it here now that I am able to post here.

As you can see by the screenshot, the carts and little trading boats are missing from the map. I know it sounds rather petty, but it really does make the map look more alive. At first I thought it was because of patch 1.3, but then I decided to reinstall the game. I tried playing at version 1.0 - nothing. They were still gone. I patched to 1.2 - nothing. Still gone for that patch. I reinstalled patch 1.3 and it, of course, is still missing. At first I thought it was 1.3 causing it, but now I don't know what to think. Does anyone have any ideas? I asked the question on the official forums, and someone said it was a key that you press to enable/disable the carts and trading boats. I asked about the key but they never replied. Does someone know of a key to press? Help is appeciated. ~:) ~:cheers:
