then it's incompatible with other mods that reads it as a leave. for example passable leaves installed, player cant pass natura leaves. another example, better foliage mod; theres no extra leaves on natura leaves... plz fix this.
octarine-noise/BetterFoliage#164
OreCruncher/DynamicSurroundings#199

Those mods should really be calling Block::isLeaves then instead of doing an instanceof check. Why do it the hard way when there is a base method?

thanks a LOT!

That's actually a very good point :)
