That's a problem i've asked for before. Now with v15 i cannot see from the ground the top of the Towers :( . That's why i have another blockland installed with v13 so i can see them perfectly. With v15 the max draw distance is 1000, and i need minimun 2000 (you can see that in options, now it says "max draw distance" instead of "draw distance" like the previous versions). I've tried with the mission editor, but increasing the value above 1000 does nothing.
