Hi,

Just upgarded my version of Unity from 5.1.2 to 5.2. Getting the error below in an existing project of mine. Any thought on how I can diagnose what’s going on?

Thanks,

Never mind I found the script that was the issue.

I’m having the same error and can’t figure out how to fix it. Could you please help me out?

In my case it was me trying to make a singleton class that derived off a network behaviour.
