Similacrum DISSAPEARED when auto navigated to stash tab

i have a background recording going , where we can clearly see that my similacrums i JUST bought (2 for 1 div) just absolutely vanish. ive looked through every stash tab i own multiple times, then went back to look at the recording. but the recording clearly shows the similacrums just absolutely vanish into thin air.

help.......

That's really weird
