Images don't display after import

[luksl]

I wonder why imported pictures are not displayed after CSV import (are not generated during/after the import). After each import I have to regenerate thumbnails. Why is that necessary? I think it was not necessary before.

Also, when I delete generated thumbnails the pictures are missing again - it's understandable but it seems that the pictures of the original sample product are generated automatically (not missing).
