Fog lights disappearing during animation.

Hi,

i have a swimming pool setup with a water volume and a fog volume (a fog container). Inside are some spotlights (VrayRectLight). So far so good. Now, when testing some animated shots, strangely some of the swimming pool lights disappear at some frames.
I tried, BF+LC, BF+BF, Adaptative light evaluation, Full evaluation.... nothing works. The same lights seem to disappear at the same frames.
I don't know anymore where to look to avoid this huge problem. Any hints ?

Problem resolved. the VrayRectLights were a tiny little bit too close to the spotlight mesh.
