Ok. There is a problem with imported prop names. It cuts it for some reason.
Original prop name is "_autocombine_dust_chainlink_fence_links_167"
but it imported it with name "_autocombine_dust_chainlink_fence_l" and it created a placeholder with the right name after VMF import.
I'll make some changes to how HammUEr handles the waaay too short internal names for models in the next build, which should... hopefully go live by the end of the month.
I remember there was a reason why I kept it to the internal name by default, but I don't remember what it was, so...
