I've read and re-read the "how to" page and it doesn't appear to have changed since last I used the mod, but the mappings seem to be refusing to work properly. Every tree just drops birch leaves.

I'm using:
BetterFoliage-MC1.8-2.0
Forge 11.4.14.1563

This is my leafTextureMappings.cfg file (located in /assets/betterfoliage/):

// Fully qualify the mapping in case of name clashes with mods
// Mod is mod's texture folder not ModID || after : is partial (or full match) to leaf texture name

// Vanilla
minecraft:acacia=birch
minecraft:birch=birch
minecraft:spruce=spruce
minecraft:jungle=jungle
minecraft:oak=oak

And some of the /assets/betterfoliage/textures/blocks folder:

I'm not sure if this is related or just an unhappy aside, but if the resources are reloaded with F3+T or a resourcepack is changed whilst the game is open BF falling leaf particles get messed up entirely and they choose totally random textures from the atlas (such as grass, etc.).

Yeah, I missed that one. Fix coming soon.

@octarine-noise, whilst you've fixed the reload corruption the actual mappings still don't seem to work.

Derp.
