Wrong screeshot in map details

[tcq]

1) Open a stadium map in the editor.
2) Change something and save the map.
3) Leave the editor and go into valley. Join a multiplayer server. Click the "map details" in the top right corner. The picture shown in the map details is the one of the map that you edited in stadium just a few moments ago. This is true for all maps on the server. Independent on how many maps you play, the result is the same.
