What happens: When using the fluid tank to fill buckets in order to feed a farm, the water buckets are being duped.

What you expected to happen: I expect an empty bucket to enter and a filled bucket to get pulled out. What happens is that an empty bucket enters and 1000 filled buckets are created.

Steps to reproduce:

1.attach to water source (ender io)
2. put empty bucket in
3. collect 1000 full buckets
...
