I just upgraded to 4.2 and am getting a warning in the console I was not seeing before. I don’t know if it was the 4.2 upgrade. It appeared at the same time as 4.2 but I had also recently done some overhaul.
Is anyone else seeing this (which would rule it being a 4.2 issue out)? What does this mean? I’m not willingly using react for anything right now. So sort of odd it shows up at all. It fires as soon as the engine initializes, before any of my code runs. I am using latest Firefox.
