As for the range thing, I was simply explaining why I don't increase my sight range much beyond 15. The AI doesn't seem to be able to handle the ability to see further then that because it doesn't make logical decisions on when to shot and when to move. But, ultimately, my point was that even when I have tested with higher sight ranges, I didn't notice alot of grenade use nor alot of grenades being tossed by npcs well beyond what the max range should have been.

As with all bugs, if I can consistantly recreate it, I can usually fix it
