I am trying to get a Basic Canning Machine to make water cells.
If I put in an empty cell then a water bucket, I get, as expected empty water bucket + water cell.
If I put in the water bucket first though, the water bucket is immediately turned into an empty water bucket.
I thought it might be because the canning machine has some kind of internal storage. So I pumped it full of water, then put in a water bucket first. Same thing happens. The water is destroyed.
Is this the expected behaviour?
