Yes, I don't know what was going on there. Probably a result of debris lying around on track. There have been many crashes in the first hours too. Also it has been said that many teams started with wrong tyre pressure settings expecting different weather, not sure about that though.
No GT2 this year since there have been not enough competitors, and the small teams are complaining about the increasing level of professionality and the ruthlessness of the GT3 teams.
