I didn't see a point in that topic so I merged it with this topic.[br][br]Added: [time]1175472426[/time]Had a chance to look at that landscape and see what you mean. Sorta.
I can see the streaks in the landscape and the blocks dissapearing. But this only happens at a distance. And I think that problem could be related to saving the landscape too often. Other than that, it appears normal.
