Issue description: I'm trying to make a bucket filler but it is destroying lava if the system has more than one bucket of lava in it.

What happens: My system fills the bucket and returns it, but the constructor somehow places two buckets worth of lava. This happens even when the constructor is alone without the bucket filling system.

What you expected to happen: The constructor should place one buckets worth of lava and no lava is destroyed.

Steps to reproduce:

1. Setup a storage system with fluid storage
2. Add more than one bucket of lava to the system
3. Place a constructor with empty space in front of it
4. Setup the constructor to place lava

Does this issue occur on a server? idk, probably
