If they can fix it so that it doesn't cause a delay, let them fix it. A18 is presumably still in the front row, so the libero *can't* replace her.

If there's no delay in fixing it, let it go. If A18 has gotten back to the bench area, we have an illegal replacement, team delay warning, put A18 back on the court, and resume play with the correct server.
