I have a scene in which I am moving a number of layers including on with reflector. When I render it the layers move but reflector doesn't update as the layers move. Have tried it about 6 times with the same results.
Would you be able to send me your .aep file (no media files necessary)? I'd be happy to take a look.
We just fixed an obscure bug relating to certain scenes. I'd like to see if your scene falls into this category, or if there's another problem.
