I agree with you, same happened to me: scene which took about 100 hours now just unworkable. I really appreciate that developers support modding community, but it was very small gap between releasing editor and making contest, very small time to make some patches and remove bugs. I do not blame anyone, and I also give regular feedback about bugs and crashes. Just feel upset for me and other people who spend much time on corrupted scene. Really hope that they can be restored after next patch.
