Crash after world load: "Cannot invoke "appeng.api.storage.data.IAEItemStack.getStackSize()" because "request" is null"

[unilock]

I was visiting a friend's base when I saw their AE2 system wasn't receiving power due to a wiring misconfiguration. Upon reconnecting it, the server crashed with the following error from AE2:

java.lang.NullPointerException: Cannot invoke "appeng.api.storage.data.IAEItemStack.getStackSize()" because "request" is null

This error and crash now occur every time the server starts and the world is fully loaded. Downgrading AE2 as far as rv3-beta-418-GTNH did not fix the issue.

AE2 version: rv3-beta-427-GTNH-pre

Duplicate of GTNewHorizons/GT-New-Horizons-Modpack#16978

Caused by PR #545 (and already fixed)

Downgrade AE2 and AE2FC or find the fixed jars I posted in Discord

@hiroscho If this issue is caused by that PR, shouldn't it have been fixed by downgrading AE2 to rv3-beta-418-GTNH?

EDIT: Oh, I guess I had to downgrade AE2FC, too.
