The answers on this are varied. You've seen some of them above. The 'best' way to do it in my opinion is to treat them as you would a familiar for replacements.
The opinions range from
1) NO! It is now GONE, you suxxsor!
2) Treat it like a familiar for replacement rules
3) Make another one tommorrow. If you want to wait that long. They're free, cheap, and easily replaced.
4) In fact, not only are they free, cheap, and easily replaced, the rules just say that you can make 'em, not how many or how often. Make FIVE!!
