Bug fixes.
Just opened up my project to test the fixes and got a black screen in some layouts... Ashley are you aware of that bug?
I narrowed down the issue and opened a new issue here: github.com/Scirra/Construct-3-bugs/issues/3934
It's impossible to tell what bug that could be from a single sentence description like that. In general if it's not filed to the issue tracker already, it's probably not a known bug.
