Yes, I’ve seen this kind of pop up at times. My guess is it’s more likely to happen if the version of Unity is not too different from the old one (maybe just one or two generations more recent).
Anyway, I’m more than halfway into the tutorial now and that’s the only change I had to do (btw, this is a very nice project to do 🙂 ).
About the lines where I swapped the definitions of screenSW and screenNE, the problem was not the script but my camera. It was set to perspective instead of orthographic.
