I changed the behavior of magma to be fluid. You can now swim in it, and although the pleasure will be intense, it will be rather short lived. Items and projectiles that fall into it are destroyed. The current of magma will carry you and the animals, just like water. Magma now flows further, up to 4 blocks from the source (in 1.10 it’s 3 blocks).
The purple screen issue with invalid texture packs is fixed. I also fixed the problem with block icons when texture pack was changed. They now re-render correctly, and you don’t have to restart the game any more.
