Sorry to bother you with it.

But ever since i used it i havent had any fallen leaves working.

BetterFoliage-MC1.8.x-2.0.15.jar

Is there any whitelist or anything special i need to set up in my config?

i got leaves like this cause of invisible blocks under snow layer.

The issue seems only for Conquest leaves, i have BoPlenty and no problems there.
