When using FerriteCore on latest version of NeoForge it crashes with:
crash report
Nothing helpful in latest/debug logs but here:
debug.log
latest.log

Minecraft: 1.21.4
NeoForge: 21.4.87
FerriteCore: 7.1.0

I will guess it's because of the 21.4.84 NeoForge update, where it was announced on the Discord server about changes in the ReloadListeners

Fixed by 4230bed. I have uploaded builds to CF and MR; waiting for approval now.
