When I chopped a log with my axe the animation was green so I went to see what else it affected so far it affects birch and oak logs, cobblestone, crafting tables, double stone slabs, tilled soil, and fences. After that it went from green to brown.
What I expected to happen was for blocks to break normally.
Steps to Reproduce:
1. find a block listed above or try to test if the bug works on other blocks.
2. try to break it.
3. it should break with a broken animation.
