Not Enough Crashes crashes (ironic lol) when using Iris with it.

I use both not enough crashes and iris together and they work fine. Your crash must be caused by something else. Please attach a crash report.

Seems like it was just Sodium Extra. I had the wrong Sodium Extra file installed and I guess I forgot to test Not Enough Crashes with the new one.
Everything is working again though.
