Describe the bug
The speedy hopper crashes the game when inserting into an interface from AE2
crash-2023-08-24_15.22.35-server.txt

To Reproduce [Optional]
Steps to reproduce the behavior:
place a speedy hopper from essentials inserting into an interface from AE2
make sure the network is powered/online
game crashes

Thus far, I've been unable to reproduce the issue. The following setup works just fine:

(the lower hopper is pointing into a flat ME Interface)

Items inserted into either are successfully transported into an ME Drive when one is attached (not pictured above).

This is likely a problem with something in one of the Ars Nouveau related mods.

The error from the above log is:
java.lang.ClassCastException: class gripe._90.arseng.me.storage.GenericStackSourceStorage cannot be cast to class net.minecraftforge.items.IItemHandler (gripe._90.arseng.me.storage.GenericStackSourceStorage is in module [email protected] of loader 'TRANSFORMER' @24876a7e; net.minecraftforge.items.IItemHandler is in module [email protected] of loader 'TRANSFORMER' @24876a7e)

the mentioned class gripe._90.arseng.me.storage.GenericStackSourceStorage is coming out of Ars Energistique - the Essentials hopper asks the ME Interface block if it has an ItemHandler, the Interface says it does, and then returns an object that isn't an Item Handler; that's on them.

However, as mentioned, I'm unable to reproduce the issue; the above screenshot was taken on a game running the following mods:

MC 1.19.2, Forge 43.2.21

appliedenergistics2-forge-12.9.7.jar
ars_nouveau-1.19.2-3.17.10.jar
arseng-1.0.0-beta.2.jar
curios-forge-1.19.2-5.1.4.1.jar
essentials-1.19-2.15.5.jar
Patchouli-1.19.2-77.jar

Note that this includes Ars Energistique, but there's no error; it may come from one of the other Ars Nouveau related mods that you have installed.

I have also been unable to replicate it so I suspect it was a freak issue with Ars Energistique. I'll look into it on that end.
