Hello! First I want to say, I have no coding experience at all! I am an art teacher, and my students are working on designing an environment for a game. Not any scripts or coding. One of my students did something and now there is an error and the game will no longer load.

I believe it is the same issue that this person is having, however, I am so inexperienced that I cannot figure out what they did to fix it.

Thank you so much!

To fix this, you can do the following: Make a checkpoint Branch off the checkpoint Switch to the new …

I have fixed it in my fork: PlayCanvas | HTML5 Game Engine
