I think this is probably a bug in Exposure, so I'll close the issue for now, but feel free to update if you can narrow it down to a specific incompatibility that involves Hex Casting (ie. less than several hundred mods :p).

Only when adding Hex Casting did the issue occur.

I did just remove Exposure and it loaded in, but now there are REI crashes and some insanely time consuming error in the logs
[Render thread/ERROR]:Serializer: Error writing recipe to packet

I'm not going to ask you to troubleshoot this, I think I will just give up. Thank you for the help :)

This error doesn't seem to be related to Hex Casting. Are you sure it only happens when Hex is added? The actual error is coming from a mod called "exposure".
