This is correct: your restart file does not have any box information in it,
and it should be there. You can check yourself: the box information is
the final line of the file, with 6 numbers (x,y,z and three angles, which
are probably 90.)

But with only 24 atoms in your system, do you really want this to be
periodic? Amber is not designed to handle crystals with very small unit
cells, or otherwise extremely small periodic systems. What is the chemical
system you are simulating? How did you set it up in LEaP, i.e. did you
use the setBox or solvateBox commands?

..hope this helps...dac
