Something Weird Bug

i installed the latest patch (1.4x) and i went in game and the trees were divided, black tree on left and white tree on right,they're split in 1 tree... how do i fix this weirdo bug.

example:

|B |W |
|L |H |
|A |I |
|C |T |
|K |E |  ---------------> They're divided in one tree.
|  |  |
|T |T |
|R |R |
|U |U |
|N |N |
|K |K |

1.41 graphic pack fixed this.
