Rendertime through the roof on some frames

[Olli96]

Hi Vlado and Tashko,
sorry for reporting back so late. Tashko, you were right, switching from dynamic to auto fixed the problem! Another side-effect is that the scene now renders almost 5 times faster, it went down from 20-30 sec per frame to 3-5 sec. That was really helpful, thanks for the great support.
