Gun prop dissappears when exporting clip in sequencer

Hi everyone,

I have this problem and I don’t know where to look.

I have attached a gun prop to my character’s right-hand bone. I have animated a sequence and it all plays out well except for when I render an export
of the animation, the attached gun prop disappears. As if it was never placed there. What could be the problem?
Thanks for reading!

Kind regards,
