If an object from a subarchway is removed and that subarchway vanishes, does that object vanish? What about animals? Or pokemon?

And if so, if raw material from a subarchway is removed and used to make something does it vanish along with that subarchway?

Koishi has an outfit made of life fibers and with the KLK characters vanishing the archway that the fibers were retrieved from is no longer there. The plot to make and get it working was done in pieces over the course of a year though. I'd be sad to see it go.

Thanks in advance!
