Hi Ashley / Tom
I can't preview my game after the latest update - all I get is a black screen and no error messages.
Everything was fine before 66.2. Exporting the game works.
I don't know what to post in the bug report as there are no errors and you require a small example (I can't send my whole game).
*** EDIT ***
I copied everything into a new file (wasn't fun lol) and it works. Somehow the game got corrupted after the update, not really sure.
