Describe the bug

I have a device to automatically generate Fluix Crystals.

up side place ME Formation Plane, down side place ME Annihilation Plane, other sides place Crystal Growth Accelerator.
In the old version everything is normal, but in the new version of the generated fluix crystals will be ejected out of the region.
I tried to put some Cable Facade place in the up and down side to block it from eject, but not working.

To Reproduce

In the new world up side place ME Formation Plane, down side place ME Annihilation Plane, other sides place Crystal Growth Accelerator.
Then create the processing repice and use it

Environment

1.16.1-forge-32.0.105
appliedenergistics2-8.0.0-alpha.2

Keep in mind the water physics in minecraft did change. Thus it might need new approaches.

I'm currently trying to find a working setup for 1.16 that doesn't eject half of the crystals in a way that leaves them undetectable by the annihilation plane. An extra gap above the water will stop them from landing atop the formation plane, but unfortunately they can still float on top of the water surface with the new item water physics. Somehow this causes the annihilation plane to be unable to detect them. Maybe the items are actually in the block above the water line? Crystal setups are like 50% lossy as is though lol.

Make sure you are on the latest version, there were some fixes to annihilation plane bounding boxes and fluid crystal reactions.

Although the swapn area is reduced, it still floats on the surface,a new solution is to Annihilation Plane place in top side.

@SAGESSE-CN Thank you for the advice. I will try that with the newest release.
