Problem was, that, although the mosaics had no acquisition time (or actually date), they had the acquisition time offsets for the seperate slides. So in the end we had 1395 volumes (which should have been timesteps) with the same starting time. And thus they where considered separate images. And unfortunately handling the images is quadratic :-( .

So, it didn't crash - it just was very slow with 1395 images.
