Hello guys i was working on this nimage untill most layers exepct one disappeared, i don't remember how many, the smoke effect layers, the background layers all disappeared. Whats strange is that the product of those layers is still there, the final image is still there...

i tried window - layers (F7) and it looks like PS6 thinks that thats the only layer

I'm also sure i didn't merge the layers by mistake

can someone help? Thank you!

In the Layers panel, I see that the filter for smart objects is being applied (it's the smart object icon to the far right of "Tipo" (Kind). Deselect that filter, and you'll see the rest of your layers.
