Patch release for r189.
There is a fatal flaw in this build, every time I create a new layout (right click create new layout) it will duplicate my other layout and then when I empty out the layout it destroys my project making it unusable. I have no global anything on. THIS SHOULD NOT BE LISTED AS STABLE IN MY EMAIL
I just tried what you described and it worked fine. We also have no other reports of any related issues. It's usually impossible to help from comments alone, if you think there is a problem with Construct please file a bug following all the guidelines: github.com/Scirra/Construct-3-bugs - we need all that information to be able to help.
