Hello, I tested the Desktop version and the WebGL version and found 2 problems in both versions.
When adding an object to the scene, save and press play, the scale and position of the objects changes and throws the objects out of the scene. The second problem I encountered, when trying to add a new state, it will not be added to the scene. Left mouse button doesn't add it to the scene, I tried every keyboard combination and still can't add a new state.
