System.Reflection.Emit.AssemblyBuilder doesn't exist in target framework.

Hello,

I can't seem to track down what uses this. I wish Unity would show where it's being accessed from. Any ideas on how I can figure out what feature I need to change to remove this error?

Thanks,
Jason

Okay, I found it. But only from trial and error. HOTween was the culprit in this case. There has to be a better way than delete-build until the error goes away.
