Describe the bug
I set up a very simple network trying to automatically put water from the world into an ME system. I am attempting to use a Fluid Annihilation Plane for this. Screenshot of system: https://i.imgur.com/krE0QAj.png (the export bus is configured to water, the storage cell has space, the system has energy)
The system was fine to import/export fluids in the tank, but the annihilation plane refuses to work.

To Reproduce
Connect ME Drive to Fluid Interface and a power source.
Stick a Fluid Storage Cell into the ME Drive.
Connect Fluid Interface and ME Drive to Fluid Annihilation Plane.
Connect ME Drive to a fluid tank with a Fluid Export/Storage bus.
Place Water in front of Fluid Annihilation Plane.

Expected behavior
I expect the plane to take the water source, and stick it somewhere into the network. This is how regular Annihilation plane works with blocks.

Attempted workaround
I gave it a lot of options for where to put the fluid, but it apparently doesn't like any of them.

Environment

• Minecraft Version: 1.12.2
• AE2 Version: rv6-stable-6
• Forge Version:14.23.5.2831
  Tank used is from Mekanism. This tank works with import/export buses while talking to the drive/cells, so is probably not the issue. Everything else is from applied energistics.
  Modpack is SkyFactory 4, but that should hopefully not affect the behavior of this small isolated system.

You cannot grab water from a flowing water block. That is basic vanilla behaviour similar to buckets.

That is a source block. A vanilla bucket picks it up just fine.

I'm having this same problem.
