Expected Behavior

the EMI plugin to load all the way and not error out

Actual Behavior

the plugin errors out here, and throws an IllegalStateException, because remove has been called on iterator before you call set

Steps to Reproduce

I don't know if another mod is inadvertently causing this, but as the pack I am making is unreleased, I can put a curseforge zip here. It happens when gregtech loads the EMI plugin

Additional Information

edit:
JAOPCAGTCEu seems to be what is triggering the issue, but regardless the way you are calling set is unsafe
