BWM v1.2 for 1.11.2
Forge 13.20.0.2230

Just added it for testing and it didn't survive the init phase^^

I will be porting to 1.11.2 once the new content update is released, I know i could port it in 5 minutes, but I don't want to. I am waiting on some things to release a new content update, which is basically a rewritten form, from there it will be ported to 1.11.2

You should give the port to 1.11.2 a try.
I did finish the update in a few minutes but there were some problems with the forge biome dictionary :/

I used the solution from the third post to get it working. Here everything you need:

for gradle:
mc_version=1.11.2
forge_version=13.20.0.2228
mappings_version=snapshot_20161220

this.worldObj changes to this.world

and for your common proxy I changed the init() function

thats all :)

K, thats a word. But for now I've got something functional. ^^
