I found one but it didn't backport the features I wanted. It had blocks, but no mobs or structures. I have Et Futurum, but it doesn't have the stuff beyond 1.8.
I would like the mobs and structures from newer versions to be backported into 1.7.10.
Why not just update, might you ask? Most of my favorite mods are only for 1.7.10, and I have yet to find enough of my favorites to warrant moving on to a new version. I'd be losing far more than I gained.
So what I want, is a backport of the Woodland Mansion, the mobs found within, llamas, blocks... in 1.7.10.
If anybody can do this, I'd be super happy!
