ATM3 Remix V1.5.2
ElecCore-1.12.2-1.9.452

Let me know if more info is needed

I see you are using Sponge.
Sponge is unfortunately not always manipulating forge events properly
Changing "supressSpongeIssues" to true in the eleccore config file should resolve this.

Please re-open if the issue persists.
