About this Mod

What does it do?

Makes so that naturally generated leaves don't decay up to 8 blocks instead of 4, which fixes big jungle and oak trees. Also ignore the modloader, i had to choose one.

Forge (Leaves dont drop when broken with shears, they also may not decay after breaking all nearby logs, other than that it's playable)
Dynamic Trees (Crashes the game)
Anything (probably) that changes arr.class (BlockLeaves.java)

Works only on 1.12.2!
