When trying to designate either the factory or the altar (or tank) using the ritual tinkerer, the first block for the range will be designated, but shift right clicking with the tinkerer anywhere else provides no message of any errors or confirmation.

I've never played with the ritual tinkerer so it is possible that I need to implement support for it. I'll have to look at BM code to make sure I've not missed something.

Sorry, I forgot to mention I am playing on 1.5.1 Beyond.

Incidentally, how did you designate the ritual targets without it? Like, on activation does the ritual search a certain range for the factory and for an altar? None of my single-player tests seem to have worked to get blood out of the factory in any capacity.

I basically place the ritual above the factory and the altar above the ritual, very much like the Well of Suffering setup. That filled the altar for it me with an orb in it. I could also place a tank in front of the factory and it would fill that instead of the altar. The ritual uses the same range values as the Well of Suffering as well.
