Fixes Centrifuge not working

Created by: 9600bauds

This one was actually my fault, touched so much sanity I was bound to fuck one up eventually. I structured this as a "do the thing if you're sane" check, it was actually a "don't do the thing if you're insane" check, which ended up being a "don't do the thing if you're sane". Fixes #8208 (closed)
