Is there an existing issue for this?

• I did not find any existing issues.

Current Behavior

Placing a fluid tank that has fluid contents will void its contents. In addition, breaking / picking up a fluid tank will show it as empty in a player's inventory, but when placed back down it will 'regain' its fluid content - unless its content is altered before placing it (such as by filling it with the same or a different fluid), in which case placing it will void it instead.

Recipes that take place in enderIO tanks, such as converting concrete powder to concrete, don't function in enderIO tanks under some conditions. This appears to be the case for fluid tanks which have lost their contents as above, but I unfortunately never figured out exactly what conditions are necessary to cause it, and it may happen in other cases as well.

How to Test

1. Fill a fluid tank with a fluid, such as water.
2. Place the fluid tank; it will be empty.
3. Fill the placed fluid tank with a fluid.
4. Pick up the fluid tank; it will appear empty.
5. Place the fluid tank back down, and it will 'regain' its former contents, or
6. Repeat step 1 and observe state 2 again.
7. Fill the placed fluid tank with water, and place concrete dust in the top right slot. The recipe will not complete.

Identified the recipe problem as the same as #768 and the bug causing the item not showing fluids has been identified. Thanks for the report :)
