I get the above error when I am running my game. I do not edit the Gui in code so I am confused as to why this appears. It began appearing when I was editing code that saves variables to a serializable class and then serializes it.
I get this message popping up constantly in the Linux version of Unity 5.3.1f1 20160106, no idea what’s causing it, I’m not doing anything fancy at all
i get this in pc version too. im 5.3.3 tho
