I got a Tier IV altar, 9060 LP
but the log recipe is not working for me...

No particles, no effects, no LP draining or something
The recipe in JEI is showing logWood, as far i know din't support BloodMagic support OreDic recipes in bloodaltar, but that could be wrong from my on
either way, its not crafting.
was not working in previous versions

Forge 1.10.2-2094
Blood Magic 2.1.0-65
Blood Arsenal 2.0.1-11

Should be fixed, was a Blood Magic API thing that I did not code properly.

Unfortunately you'll have to wait till the next BM release.
