Strange crash with NEI?

[HyperMan19680]

So it seems when I have the 2.1.0 version going with 1.7.10's NEI 1.0.5.120-universal I get this log and it crashes. Removing NEI is not an option as some of the other mods in the pack require it.

Use UniMixins.

If nothing else, I'll close this.
I'd also pinned this for it's a common question asked by players.
