When i tried to use Thermal Expansion ducts to transfer stone into the blood altar it placed inside 17 stone and wasted half of the LP inside because it was runing and not making anything. I didn't wait for it to finish making because it was probably not gonna. When i tried to kill a baby zombie with the dagger of sacrafice it didn't one shot it even tho it was directly on top of the altar im playing agrarian skies.

These are not bugs. When items are added to the altar in any way aside from a player placing it, the items will starts stacking normally. When the items stack, they will use as much time and LP as if you had done them one at a time.

The forum post say that the life essence of babies is "Impure", and as such can not be used in the altar. This applies to baby zombies as well.

nvm my bad i guess i never read on this mod wanted to go blind and see what happens..
