Apparently they answered this question in a QnA and it's what possibly they're gonna write for future IDFB episodes that the recovery machines can't "obtain the DNA in the air of the objects" (fucking insane revelation) so they may only be recovered by using that machine.
They still gotta figure out why doesn't black hole just dents it so everyone can get out.
Then again at some point in idfb he becomes the size of an actual black hole which makes the entire incident of BFB happen when flower wants that jar.
